PROBLEMS:
Low RPM: it stays at 500 RPM and then goes down to almost 0 (car feels like it’s going to stall) and then goes up to 500. I recently change my battery so I had reset the ECU, after reset the RPM goes up to 1200, and next day goes back to 500 to 0 cycles again. I also clean my throttle body but nothing improves.
Rough idle: just rough… :frown:
4 or 5 cylinder: the car feels weak as if I am only running on 4 or 5 cylinder. (Engine light not on and no error code from ECU)
Backfire from exhaust: pretty much any RPM and any speed backfire comes and goes. At first I thought maybe one of my cat is bad, because it only happens with driver side’s exhaust (No black smoke)
Spark plug? Injector? Coil? Timing belt?
thanks in advance
