my 1994 twin turbo only has 60.000 miles.But recently the check engine light is staying on and the car seems to me to be running rough.I recently had the plugs changed and it seemed to help a little, however it still doesn't ride like it did in the past.A few years back this happened as well and when the light was on the car ran really rough,however I noticed if I sat with my foot on the accelerator for a short period of time the light would go out and the car would return to running really smooth again.Unfortunatly that hasn't worked this time.How can I know for sure if it is indeed one of my injectors is bad,and if so which one? Any help would be greatly appreciated. Thanks, Kelleigh
