My car was accelerating on its own but has stopped doing that and now is stalling and has a rough idle Mechanic's Assistant: Is the rough idle intermittent or consistent? Hardly noticeable but I believe it’s constant. It just doesn’t feel right Mechanic's Assistant: What is the make/model/year of your car? Pontiac Bonneville SE 1994 Mechanic's Assistant: Are you fixing your Bonneville yourself? What have you tried so far? Ive replaced the air filter, which was filthy, but it seems like the idling got worse ironically Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I accelerate get “check gauges” it stalls while driving, then “service engine soon” light. Starts up right away just to repeat that signaling process
