I already changed lots of parts to fix this problem but every time failed. I'm going crazy with this!
distributor cap, oxygen sensor, throttle position sensor, spark plug, valve cover gasket, coolant temperature sensor, oil changed.
and also cleaned throttle body and egr valve.
it was pretty nice right after cleaned egr valve yesterday. and today it cames again with engine check light turns on once and go out.
i also checked diagnostic but nothing comes out.
any idea can be helpful.. please help!
