2004 cavalier 2.2 ecotec auto.
Things I've just replaced;
Spark plugs, fuel filter, oil, air filter and valve gasket. (Spark plug showed normal wear)
cleaned throttle body And iac motor. (Don't know if that motor is working 100% but wasn't to dirty)
150.000 miles starts right up. (Most the time) day or more take few cranks.
When in park and neutral Idle is like butter. Than in drive its rough more like a vibration type. And its slightly hesitating/rough until 10mph.
Aslo its like the car isn't taking off like you would anticipate. More on sluggish a little bit. I had a 2002 cavalier with the non ecotec motor. Less horsepower and it seemed to take off smoother and faster! :(
have the same problem?
