Does this happen when you are in idle or when driving? Are your plugs and wires in good condition?

 

any CEL's? you can try clearing the ECU memory and see if that helps. if it does, its a sensor giving false readings and the ecu is "learning" the new bad data. it might not be bad enough to trigger a cel, but bad enough to cause poor running. also, check to see if the O2 sensor is good. cold be any number of things...grounding comes to mind....

 

happens when driving

and also no check engine lights...i

 

probably the o2 talking ****, or maybe a plug. try those first
