While driving, I can feel my car "putter", I step on the gas pedal and all the gauges drop down. It takes about 3 times of turning my car back on & pressing the gas pedal before the car will stay on and move. We took it to a mechanic and the engine light was reading a misfire. they changed the spark plugs, and the car is still doing it. they said their only other thought was the coil packs. If other people are having this problem, maybe this should be added to the long list of RECALLS!!!!!!

Parked it for the night, it was fine...woke up the next morning to it misfiring. Put in injector cleaner, chaned boots, plugs, and coil. Also chaned out fuel filter. Next step is ignition coil. Only code coming up is a random misfire code. Still in the process of repairs. I have a 2006 Saturn ion 2 with 71350 miles.

Same problem, many trips to dealer and unsuccessful repair. Went to junkyard and purchased used ignition coils and installed myself and it fixed the problem for a time. Eventually, the problem returned

Started by stalling and idling. Got coil pack and spark plugs changed. Ran great for a couple miles then engine light started blinking and the exhaust sounded loud while accelerating. Misfire in cylinder 4. Brought back and said it needed a new coil pack which I just did. Ran great for a couple miles and misfires again. I'm so upset. I can't afford this.

strong gas smell, chugging, die when idling if I didn't keep foot on gas. running really rough. tried replacing the ignition coil, control module, and spark plugs. still ran the same, so I took the ignition coil and control module back to the part store. I then replaced the fuel pressure damper. and it still runs the same. I have yet to figure out what the problem is. when I went to orielys for a diagnostic, it read that my engine was getting to much gas. really would like to know the problem, instead of keep replacing parts.

I was driving 18hrs from FL to NJ when in the final 2 hr stretch of the trip the engine began to misfire. The check engine light was blinking while driving. We stopped at an auto zone to check the code. It was a in misfire cylinder 4. We changed the following items. Spark plugs Coil pack Coil neck and spring Ingition module 1 Injector It ended out being the coil pack. Engine idles fine now but between 600 and 1700 RPM the engine is very loud then calms down after. I don't know what this issue could be.

Chevrolet service could not determine cause after repeated service calls. Throttle body cleaned, plug wires replaced twice (coil failure indication). I have seen check engine light, traction control and power reduction warnings. Misfire code is present and there is occasionally a noticeable miss in engine when at idle. Error lights can be cleared by shutting car off, waiting and restarting engine. Frustrating - GM quality is lacking.

I ran across this looking for a solution to my son's 1998 Saturn wagon. He was driving home and it sputtered/shook and died on the freeway. A friend who is a mechanic looked at it after we had it towed and said it was the ignition module. We will find out if that did the trick. Supposedly it did.

I have changed my coil pack twice since February. On 8/29/2015 i was on my way to work and as I turned the corner, It died. I was putting or misting until I pulled in the shopping center near by. When I turned it off and back on, my car started shaking. What to do? Can't afford another car right now!
