Tonight when I started my GM, I could feel a miss while idling. When I put it in gear, I could really feel it. I had to drive about 4 miles to my brothers house, and about 2 miles down the road, the CEL began flashing for about 10-20 seconds, then went off. The car continued to run like crap. When I left my brothers house, the car was still running like crap, and about halfway home the CEL came on and stayed on and the miss was still present.
We've gotten 6 inches of rain in the last 5 days and the car has ran great until today. It rained today too, but nowhere near as bad as the past 5 days. Not sure if this could be contributing to the problem or not. I plan on having the codes checked tomorrow. I just need to know how big of a risk I'm taking by driving it.
