Thanks for the simple explanation without using unnecessary and confusing terminology. You were a big help with diagnostic info I can look for using my equipment. Keep up the Great work ! 🎉
You sir is what we can call a master mechanic, you have a way to explaining things that make sense and walk us through it, and testing and why. You have me waiting to watch more. Thanks for helps us learn! Don’t change!!!
Very well explained in a way that non-tech owners can understand and, more importantly, fix on their own at little or no cost. Thank you for sharing this Jem.
Dude, this video should have millions of views, I just learned something that you don't in the school, today, valuable information. Thank you so much. Bless.
You are a professional ASE Tech. You are what all Techs should be like. Honest. Never upsetting. Just good to the core. I wish I can find an honest shop that determines what needs to be repaired and helps out if its an easy job and not upselling.
Hi K Du thanks again for a great demonstration on how to trace and repair fuel trim problems you’ve been very practical and to the point I’m learning a lot from your videos and very impressed with yoy Autel thanks again and be safe
Sir, youre a great instructor. Your explanation of the fuel trims helped me fix my vacuum leak. It was the fuel injector O-rings causing my bank 1 to go lean. I replaced the O-rings and my fuel trims are now at 4.7 and 4.7. No more dash light. Thanks again sir!
I agree with other comments about your ability to explain the scan tool data. Very logical and understandable explanations. Excellent .. now a subscriber.
The Smoke Test really helps a lot, the basic and simple way of trouble shooting the problem accurately. rather that spending parts while doing trial and error. It really helps alot in saving money. Thanks alot.
It's 6am I'm watching this.. I work on Benz primarily and got a camry with this code. Your information was great I will apply this diag to the camry to help me . Thank you
😮 I just want to stop and say how crazy good this video is you explain this I thought nice educational teacher. I haven't got the whole grip of the concept yet but just the best I have seen a mechanic video someone's explaining step-by-step in a real simple form that a child could probably learn this is really good sometimes I do my video and I know what I'm saying but at some point I start to get in my head like I need to rush
Thanks again body, nobody explains and troubleshoots like you, very sample to understand for DIY, I suggest you to open a teaching shop, I’ll be your first alumni, but unfortunately you are little bit to faraway from me, but your videos are a masterclass to learn. Thank you thank you.
Like ur channel !Keep bringing different situations n issues with different approaches in your diagnoses!! Like I said before, ur a technician, not a Parts CHANGER!
That was one of the many codes on my 2003 Chevy Express 3500 LT. Had a permanent MISFIRE also for years. Just wrapping up an reman engine swap that i got from AutoZone and discovered some bolts on both my exhaust manifolds were broken clean off and there was lots of carbon residue on the sides of the engine. I'm assuming i was sucking air at this point. Before this discovery I changed spark plugs, plug wires, ignition coils and O2 sensors to no avail. Even did a live scan one time and one of the O2 sensors were pulling 0.015 v. Oh. The engine never went into closed loop. EVER. I'm a driveway mechanic so i learn a lot of things the hard way. Thank you for your video, you Kind Man. SUBSCRIBED!
Excellent video, I have learned so much from this, you are a professional and did it all with a camera in one hand, so as the saying goes you could do this job with one hand tied behind your back !!!👌👌
This was a simple method, with clear explanations of your rationale behind every step. Thanks for uploading. It gave confidence that the issue I'm facing with my truck is a vacuum leak. I'm about to make a DIY smoke machine and trace the problem spot.
I have been chasing the po171 and po 325 knock sensor code. The vehicle i am restoring is a 98 Nissan altima GXE. I had a po440 and a po 1138 i believe. I replaced the evap hose's. And that fixed the evap codes. I am now tracking down the massive vacuum leak. The short term fuel trim is + 20 to 25 percent. The long term is and stays about 10 percent. I changed the 02 sensors map and maf sensors. The fuel trims on the road is totally normal indicating a vacuum leak. I changed those sensors as maintainance because of the car age. The PCV and intake bellows are next suspects. This was a good video.
Thanks, after watching video I think I have a vacuum leak in my 2006 Ranger Rover Sport. I will take the necessary steps to make sure that is the problem. I will keep you posted on my progress.
Love the vid, I had the same issue. Cracked hose, I wouldn’t have caught it if it wasn’t for you. Thank and again great video!!!!Thank you 👍🏼🤛🏼🤘🏼. PS I have the exact same car and color 😆 I knew right then I had found the right tutorial 👍🏼

K you did an excellent job...my car has the same error minus the P420(the cat was replaced a year ago) The PO171 is something new I hope once I clean the MAF, That ista a simple vacuum leak that can fix!! Thank you
Thank you so much for your video your explanation is very good and a lot of detail. Make me to be able to understand more about motor mechanical problem
I was experiencing the same problem, thank you so much now I can get straight to the point. You've earned yourself a new subscriber, looking forward to seeing more content from you, cheers.
Very nice video explaining what all those numbers mean. I have that same code. I cleaned the mass airflow sensor but code is still there. So on to the next thing to check lol
I have the same car and it has the same problems and it had a crack at the same place in the hose. Guess I need to get me one of them smoke machines. Great job on the video and explanation. I like to work on my cars, but the issues I run into are usually the first time for that issue so I need a lot of details which you provide. Thank you.
K diagnostic thanks for such an informative cool video, you are truly a professional tech with excellent diagnostic skills, my years in automotive as a SAE certified tech back in the day was filled with learning as much as possible so I could be the best tech possible just like you, another way to check for vacuum leaks due to lean running is to use propane gas around the engine as it's running, when you hit the spot where the leak is the engine will Rev up high as long as you keep the propane gas in that spot, we used to do that in the 80's to find vacuum leaks. Love the Video and your expertise, much respect
@@KITS_Auto_and_Truck_Repair just remembered something else, the EGR Valve is only suppose to open during open throttle and when cruising but at idle it's suppose to close so it doesn't make the car run too lean, but the symptoms would be that the car runs fine when cruising but would shut off at idle cause the EGR valve would stay stuck open and lean out fuel system at idle...don't know if that's a problem with the cars nowadays with all the new technology and computer controls
@@KITS_Auto_and_Truck_Repair I had my nephews 2007 corolla towed home, I scanned it and got this same lean code , I found no vacuum leak but I took 3 spark plugs out and found the plug tips soaked with oil and combustion chamber has oil in it on 3 cylinders, 4th cylinder and plug is dry, didn't do compression test yet but what could it be?..the combustion chamber suppose to be sealed so how can oil soak tip of plugs and get into chamber? Rings? Head gasket? If it's real bad he's just gonna get a new car but I just wanted your expertise on this.

Rings? Head gasket? If it's real bad he's just gonna get a new car but I just wanted your expertise on this.
@@TheMrchris1234 it's either defective piston rings or leaking valve guides!
