2000 Pontiac Sunfire 2.4L surges while accelerating, mainly while maintaining speed.
I have replaced the TPS, Map sensor, fuel filter, air filter, plugs, coil housing and coils, cleaned throttle
body, and I have also checked for codes. Nothing shows up as far as codes are concerned. Does any one
have any suggestions?
Clean the MAF?
Still has the same issue, and I have noticed that it occurs when it is at operating temperture between 30 mph and 50 mph.
