still cant find misfire
ive been getting these codes for about 10 months now and still cant find out whats wrong with my car. p0300 p0301 p0302 p0303 and p0304. i changed the spark plugs and ignition coils, and it was been through 2 mechanics. neither of them found the problem. one of them thought it was the timing and he fixed that but its still misfiring. and sensors are sending positive feed back, and passed compression test and NOTHING! it has a rough idle but i cant actually feel the misfires when im driving, but one of the mechanics said its misfiring at around 1500 RPM. the misfires started happening after i changed my catalytic converter to get rid of p0420 which it did but now i get these misfire codes. one of the mechanics thought that was causing back pressure but the other mechanic said its not (he checked that). I DONT KNOW WHAT ELSE TO DO! i need to pass smog test next month
