ok so i changd the tps and the isa and nothing happened but now my codes are 12-15-24-55 so i dont now how my tps is bad because i just put a new one in but i need to figure out where the isa is does anyone know were it is
well i took out the tps but i took out both sensors right next to each other because i didnt know which on it was but when i too one out it was so nasty but the tps was pretty clean and i dont know what this other thing is but its pretty dirty so im going to try and figure out what it is and buy...
i dont have one of those code things the guy that we took it to thought he fixed it but he didnt and every one was saying that it is the o2 sensor but i changed that and it didnt do anything
Hi
I have a 94 jeep yj and it has been sputtering and backfiring a lot lately.
i have already changed the o2 sensor and it is still doing it. when i first put it in the check engine light turned off and it still sputtered but now the check engine light is still on and i dont know what to do.
