Hey all,
I have a pretty gnarly 2002 toyota camry that I need to make functional for gig work.
I was running "fine" until 36 hours ago and started having misfires/jolts/rough idling.
I replaced the 4 spark plugs with some NGK autozone replacements but still was getting the rough idling and joltiness of the vehicle. I also replaced the spark plug gasket as there was oil in the wells and on under the engine cover. I also swapped 1 & 2 ignition coils and 3 & 4.
Just a few days ago I was just getting a P0171 error code, however today before all the fixes I was getting:
P0100 (Mass air flow) sensor circuit malfunction P0110 (Intake air temperature sensor circuit malfunction) P0171 (System too lean, bank 1) P0303 (Cylinder 3 misfire) and after swapping the ignition coils around P0304 (Cylinder 4 misfire).
I then bought a durlast ignition coil because money is pretty tight right now, and installed it on cylinder 4 as that seemed like the newest code and because I didn't clear the codes previously seemed like the most probable cause.
However after chaning cylinder 4, the engine would crank, start and immediately die. However the fix I found was that I would have to apply gas for a few seconds and then immediately shift to reverse as the engine would fall back to 0 RPM and then I could reverse out of a parking spot and drive. However when I would park again it would die immediately.
The car has a bunch of issues but I need it to just earn some income doing delivery work as I finish up a few things and keep applying to other jobs.
What would be the best steps here without spending an arm and a leg?
