Engine Performance problem
2004 Chevy Malibu 4 cyl Front Wheel Drive Automatic 105000 miles
I have a 04 Maluibu 2.2 liter as soon as the engine is warmed up the idle will go up and down from 1000 rpm to 500 rpm a couple of times then will return to 800 and stay there. The idle is smooth the whole time. Replaced spark plugs and gm replaced the cat because of prior issues. If the air is on it seems to be worse. If I come to a stop real slow it will come down to 800 rpm and act ok. It happens when I stop normal or a quick stop that the rpm surges. Also there are no check engines on.
have the same problem?
