Got the recall turn signal lamps fixed last week and everything was fine.

Then, over the weekend, had a new problem develop. The car (2004) started having very rough idle when stopped and acted like it only had 3-4 cylinders when you accelerated from a stop.

No DIC message, then the "Check Engine Light" came on. Called OnStar, they ran diagnostics and found nothing.

Limped home yesterday and into work this morning (never stalled, but acted like it was about to every time you start from a stop). Then, when taking it from work to dealer (2 hours later), it was fine, although check engine light still on.

Left it with the dealer today. Interested to find out what this was.

Anyone else have an issue like this?

Had my lamps fixed last week. Dealer was not very happy with the wiring instructions from the factory as they were not "plug and play". However the car runs great after the installation. I purchased the car used and experienced ruff idling until I ran some fresh gas through it, then all was fine. Did you recently fill up and get some poor gas?

this was happening with my V when I first got it, but it would reset itself when restarted. If I recall, they changed out the ECM to correct it.

Gas?

I did fill up with gas on Friday, prior to this starting, but it was from Exxon. Who knows. See what they come up with.
