I have a 98 Chevy Tahoe. Yesterday when I started the car it was running really rough. Usually it gets smoother as you drive and the car gets warm. I drove about 1 1/2 miles and turned off the engine. I paid some bills then got back in the car and when I started it it was still kind of rough. I was on my way to my bank and the service engine soon light started flashing. Hmmm, should I go home or go to the bank? I went to the bank, figuring I might not be able to drive the car today. When I left the bank, the car was driving pretty smooth. I'm thinking maybe I had some crap in my gas and it worked it's way out. But the light is on all the time now. I read somewhere that if you start the engine so many times and the computer does not sense the same situation again, that the light may reset itself. If there was just some stuff in my gas and making it's way out, is this possible? If it's possible, how many times would I have to start the engine, and how far would I have to go? I went back to the bank today and the car is running great. I am confused. Any help would be greatly appreciated. Thank you.
