You can put some magic oil in it to help to lube the apex seal. That what I did to clean it up. You also have put some two cycle oil in the gas tank. Also had the situation it was starving for gas so I replaced the fuel pump. Hope that help you out
sounds like some bad coils happened to me in the rx8 change sparkplugs and wires, get an oil change, fuel pump or fuel injectors can be the issue too in my case i changed the fuel pump since it was leaking
Check the fuel filter sock that's In the tank, it could be clogged where it let's fuel through the system, but then the resistance builds to being too much and it stalled. Also have you tried throwing in a new battery?
Tested fuel pressure lines and they were good. The batter was not even 6 months of so I knew it wasn’t that. I naught a used engine and put it in mine. Now it starts fine. Old engine must have shatted out. Tends to happen in these rotaries if not maintained
I'm afraid you're about to find out, what it means to be a rotary owner. Way better cold than hot starts is the universal sign of worn apex seals but the stuttering and stalling under load sounds like, there is no compression on one piston, but since this engine have rotors, it means, that if you blow one seal, you instantly have two combustion chambers with no compression and likely a full rotor with no compression at all, due to debris. So it could be, your engine runns on just one rotor, that also haven't the full power due to worn out apex seals. I'm not certain, could also just be a clogged fuel filter, a choked line, bad injectors, bad ignition coils, dead spark plugs etc. Even if you put new coils, injectors etc. in the car, there is still the possibility, that they are broken out of the box. This didn't happen alot but it happens from time to time and is one of the reasons for unfixable cars, becaus the mechanic usually didn't have in mind, that the new part also could be inoperational or faulty. Good news, rotary rebuild is relatively easy, bad news, most rotary experts are well aware, that pretty muche every normal workshop refuses to work on rotarys, simply because they think, it's wichcraft, what it clearly isn't and bill corresponding prizes. This is just a likely probability because this is a problem, every long time RX owner will encounter one day but it didn'tlmean that it has to be this way, maybe it's something completely different, but far diagnosis is a bugged thing.
Another thing I’ve heard is barometric sensor will fail and is a common issue that will tell the ecu to cut gas and air flow my friend had the same issue and we say a comment about it and when it was replaced it ran started and preformed like new
You had a cylinder misfire probably from running dry. The stock oil squirter sucks in these cars. Run 0.75 2 stroke for every gallon of gas. And run SUPER gas.
Never figured out exactly what it was but I swapped it for a used one I found with 50k miles on it. Now it starts hot or cold. Must have been compression failure.
Looking like an engine rebuild or swap, haven’t decided yet, Don’t want to sell it for 500 bucks. Took out a spark plug to listen for compression with a new starter didn’t hear any pauses in ticks so must be insufficient compression. Should do an actual test to be sure.
Yea man all that shaking was one rotor doing the work of two trying to keep the car on. If your compression is bad or getting worse l, a engine rebuild is in order to get that engine working again. I scavenged the internet and salvage yards looking for a used engine at good price. You could say I got lucky, with new engine it starts like normal @JTunerz
Not every issue has to do with apex seals, RX8's (including my own) have very bad fuel delivery systems, fuel pump is what's causing mine and I got one and it's getting shipped

@@giovannigarcia9760 What did you do with the old motor? I'll buy it off you if you still have it

I had a shop that thought it was witchcraft...
In reality, they just flooded it... And sold it to me with a 'blown motor'.
You had a cylinder misfire probably from running dry. The stock oil squirter sucks in these cars. Run 0.75 2 stroke for every gallon of gas. And run SUPER gas.
If you have a stock catalytic converter, you need de clog it or either just get a cat-less mid pipe
If you found the problem let me know I got the same problem right now
Its an automatic thats the problem get the mens edition with the 6 speed. Your cat is probably clogged.
I had the same issue on my car. It got worse and worse and now it wont start at all. Did you find out if you had low compression?
Yea it kept getting worse. I never tested the compression. Found a used engine and swapped it in mine. Now it starts every time hot or cold
@@giovannigarcia9760low compression very likely
What was the issue in the end? Did you get it running fine again?
The wrong gas puts stress on your fuel pump to stay alive and ends up burning them out.
Did you find out what it was? my has the same issue runs fine once it starts but dies after a while then floods.

Same issue with mine, did you just replace the engine? If the compression loss is that mean the engine is unrepairable? Thanks!

@@giovannigarcia9760 would propably Do same here then, did you Replace it yourself?
Yea first time doing it so took about 2 weeks with my schedule
@@giovannigarcia9760 thanks Man appreciate your response. 😊
Sounds like maybe worn apex seals. Remedy= rebuild.
Not every issue has to do with apex seals, RX8's (including my own) have very bad fuel delivery systems, fuel pump is what's causing mine and I got one and it's getting shipped
@@savensat Did the fuel pump fix the issue
@@savensat update?
Sounds like water in the gas. Stop buying Regular gas with 10% ethanol. Ethanol is a water magnet. Buy Premium instead.
