A 2000 Corolla is known to have gasket leaking when it is old as a common problem. Inability to climb mild inclines and rough running is odd for a Toyota 1.8L engine. I replaced fuel injectors (rebuilt, warranted set for $130) and coils and got platinum NGK plugs and at last... had the intake manifold GASKET replaced for fairly cheap. Problem disappeared on GASKET replacement after the 3 other things were done. At 275K miles on the odometer !
I have 2001 Corolla, 270K miles on it, same issue P130/P133, did replaced the plugs, fixed the exhaust, nothing worked, will try replacing the mainifold gasket, hope that fixes it.
Just diagnosed a 2000 celica with the same issue!!! Almost was going to call the O2 sensor because it would lag but did the brake fluid test and it tested positive for a intake leak. Good info!!!!
my 2000 Corolla had this problem and a replacement of the gasket resolved it immediately. Not plugs, coils, injectors, or cleaning the PCV and MAF valves along with throttle body and IAC
Same here cleaned the mass airflow and changed air filter not sure what vacuum leak its talking about other then brake boosters but hopefully its just the intake maninifold if thats the code ur getting too
@@Yeamontay Took some carb cleaner and sprayed the manifold gasket area. It changed revs and gave me the incentive to change it. No problems since changing the gasket!
South Main Auto Repair can you give me some advice on my 2005 Toyota Corolla they say it’s not my intake manifold they say I have an emissions leak and my engine light is on, I don’t have and won’t have $500 dollars to fix this problem anytime soon at a shop so how would I fix this on my own at home, this emissions leak? I’ve already got shops telling me it’s going to take them 3 hours to find the leak , sounds like some bullshit and I am a woman too.
Excellent video I have 1nrfe dvvti Low rpm lack of power need to press gas more and sound from exhaust gogogo No rough idle No codes No engine light No white smoke 39mpg atm Change spark plugs air filter cleaned throttle body inside out Any recommendations Its an electronic throttle body can drive 70mph at 3500rpm but lots of noise
Hi, great video thanks. I have the problem, which I understand is quite common on these, where the revs at idle, surge up & down around 2k revs when the engine is first stated, particularly from cold. I understand that a leaking intake gasket can be the cause of this problem, but my fuel trims look normal (around 0). I was wondering if you know of any other causes of this surging idle problem? Many thanks.
I appreciate seeing the second method as I've heard of that but it was nice to see. Regarding the first soapy water method, was the engine on??? Will you see a leak without engine on? Where did air come out of, ambient? But the second part was good.
The bubbles are made by the smoke machine blowing smoke into the intake. With the engine on it'd just suck the water in as the manifold is under vaccum.
Great how to video. Question: I have a 2006 Corolla Matrix with 73k miles, runs perfect-no error codes. Should I clean throttle body and MAF sensor just to be proactive or should I leave them alone? Thanks.
Great video , so in this example it was the valve cover gasket that was leaking ? Could you further explain why those two pids mean in terms of where the leak would be coming from if you have those values ?
They said it’s not my intake manifold and my engine light is still on ? I keep being told I have an emissions leak, but where would that be at, I can’t pay $500 dollars to someone to fix my 13 year old car it’s a 2005 Toyota Corolla CE and I am being told when I go for my smog it won’t pass unless I get the engine light to go off for good? Please help me to learn how to fix my car
Thanks Eric really neat trick. Got a maybe not so easy question for ya. What maker of vehicle scanners do you recommend for the DIY'r who wants live data feedback, on screen code assist and generally a real good quality scanner?Background - I had an Actron CP9580A code reader but I gave it to my son who now lives in Texas. The only thing I don't like about this scanner is that it can't interface with Windows 8 or Win 10 computers. They have said that they plan to release a new driver for the computer/tool for the last year. I'm getting a little antsy waiting for them. I know there is a half dozen or so good scanners out there ranging from wireless to connected and from cheap and erase codes to the lets see what else is going on type of scanners. The latter is my choice for scanner capability level.
+South Main Auto Repair Thanks Eric !! BTW, does the family like chocolate candies? or better explained Hawaiian Nut & Chocolate candies? What about some Hawaiian Jelly for those PB&J days?
hello dear I have 2003 Toyota corolla I need help you my car is start but won't stay raning I don't no what's a problem everything is good feulpump spark plugs intake air flow throttlebody camshaft senser crankshaft senser everything is put new but same problem I don't no what's problem plz help me dear
Could you also use the scan data readout of manifold absolute pressure to confirm vacuum leak? I have 1999 Toyota Corolla. Idle LTFT is rather eratic (up to 15%) but stablizes to 7% and under after long drive. It seems like maybe there's a vacuum leak at intake manifold gasket that gets sealed when gasket expands under heat? But the manifold absolute pressure stays at 10.5 inch HG to 11.3 inch HG @ idle (AC off) regardless if the LTFT is at 15% or under 7%. So, is it possible to have a vacuum leak that does not get picked up by the MAP reading? Thanks.
yusuihang Oh for sure. It is not like you are loosing inches of vacuum or enough to be registered on the MAP sensor. Your best bet in this case is to use the STFT. The gasket will seal up as it is warmed up, almost completely in some cases. They are very cheap and easy to change even if you didn't want to test it and just guess.
South Main Auto Repair Thanks. I hesitated with just changing out the gasket because on the 1999 Corolla, gasket is flat type (felt?) sandwiched between metal surfaces unlike the later (after 2003, I think) Corollas which have the rubber gasket and plastic intake manifold. So I wasn't sure if the gasket seal would improve with heat like with the rubber gasket. But I have 360k miles on the original gasket, so it's probably a good time to just replace it. I stumbled onto your youtube channel last night and like your videos a lot. I subscribed right away. I had watched ETCG videos before, but never subscribed to him. I am just a home DIY but appreciate the contents of your videos. Hope you will continue broadcasting.
Oh I see, sorry I didn't look to see what the 99 used for a gasket. Do you have a scan tool you can watch the STFT and spray around to find the leak? Do you know what I mean?
South Main Auto Repair Yes, I know what you mean. And I do have scan tool to watch the STFT/LTFT as I am spraying. I will try that out. For the 1999 Corolla, only need to remove plastic cover (secured via nuts on studs through valve cover) over fuel rail to spray around intake manifold. I had previously sprayed around other parts of the engine (throttle body), PCV hoses, but stopped short of removing fuel rail cover to spray intake (and injectors) because I thought the valve cover studs may have to be removed to take off the plastic fuel rail cover and I thought I should get torque specs for valve cover bolts first. Now, I have the torque specs for valve cover bolts but I also realize the the fuel rail cover can probably be removed via nuts on the valve cover studs without having to unbolt the studs. I know that my thought process may have excessive and ridiculous. :)
No your though process is great. To get the best results do it when the car has sat over night and is stone cold. If the intake is leaking that is when it will leak the worst IMO. Will you let us know what you find?
Help plz. 2005 Corolla with p0171. So far have changed the maf with Toyota oem part. Replaced both o2 sensors with denso. Changed intake gasket. Changed catalytic converter due to a leak. Fuel pressure reads at 49 psi. Removed and cleaned fuel injectors. No vacuum leak. Car running very rough at idle. At idle, short term fuel at 0 and long at 25. At 2000 rpm, short at -4 and long jumps to 40. Any ideas plz.
sargon khabeer Hook up a scan tool and check vacuum at idle on warm engine. It should read about -25. If it's much higher (less negative) you still have a vacuum leak which will cause a rich condition (as shown by you high LTFT). However, with a vacuum leak the LTFT should drop at higher RPM. You might also have worn injectors which are not spraying fuel properly-even though you cleaned them. You can remove and check spray pattern (videos online for how to do this) Check the plugs. What is the RPM at idle when engine is warm? How many miles on car?
i feel like my corolla s does the exact same thing its a 07 high revs right when i start it off the bat in the morning at about 2000 rpms short at -4 as well it haaaas to be my intake manifold my car does vibrate at idle not excessively but it is noticeable like at stop lights etc i really am getting tired of this any suggestions somebody, anybody?
I'm having a problems with my 2008 Matrix, I really need to floor it to get up to highway speeds or maintain speed up hills. The car does vibrate at idle, not excessively but noticeable, and sometimes when I put into gear it it feels like the engine wants to cut off. The car only has 84,000 miles and there is no engine light on. I was wondering if the problem you mentioned might be causing this.
Did you fix it? I have the same issue, maybe I'm not noticing performance decline but car vibrates, changed engine seats, cleaned throttle body, changed MAF sensor, changed spark plugs, changed fuel filter assembly, cleaned fuel injectors, cleaned air filter, changed pcv valve and hose, oh and the car still has bad gas milage, it's a 2010 Corolla xli, GCC specs, with almost 200k km now, a full gas tank of 42 litres would drive me a total of 340km in city and then I'll have to refill again.
@@JesusChrist-mz9gi Iv done just about everything you've mentioned and some on my 2010 xb(185k miles)but same here it has no change it power and seems fine except when I go in gear it wants to idle unusually low and surges when idle, the only thing I haven't done and what you didn't mention was cleaning the iac as well as the throttle body(which I should have done but was lazy), but iv done a complete tune up amongst other things and nothing has solved it. Next step iac cleaning and checking for intake or vacuum leak
You spray where the soap was bubbling on the intake.... all along the gasket seam where it meets the head. Smh. It'll naturally draw in the carb cleaner, brake clean, etc, and change those specs in the scanner. It's just another way to prove there's the leak.

I am impressed, you did a great job and you sure simplified the processes of finding a leak. Thanks

Try cleaning the intake and the mass air flow sensor. That will usually fix it.
Very good information Thanks, I will try the soapy water, I will share too

Mine ended up being the oxygen sensor. Great info tho!
Ugh.. ohms tested the O2 sensor and it showed bad. Replaced. Problem still present. Onto the gasket testing.
