maydog Posted March 18, 2005 Report Share Posted March 18, 2005 I thought I would shoot this question out just before I hook the laptop up to the car... The past week my car has been running very rough for the first 10 - 30 seconds after starting the car. After that period everything runs fine. It is only rough from a cold start. I am going to do some troubleshoothing this weekend, so any ideas on what to check. Things to think about: I recently had some exhaust work done to make room for a trailer hitch (drawtite makes an excellent hitch). They replaced the mufflers I had with new ones, significantly quiter and I think they flow less as the buttometer is seeing less activity and the tires dont break free on a WOT as often. I didn't really trust the clowns working on my car, see the post on the broken ride height sensor, but I have no access to pipe benders and welding equipment. They may have screwed something up. My water pump is leaking pretty bad, I will replace it this weekend - maybe water is getting onto electronics. I have a host of other electrical gremilins - for example my memory seat module throws all possible control codes and twitches over bumps. There may be an electrical wiring issue here ... Thats all the known conditions with the car. I was thinking that maybe an 02 sensor could not be warming up. I can leave the car in the on position for a minute and it will still be rough upon starting. Does anyone know when the car is supposed to go closed loop. I have an elmscan box that I can hook to my laptop and view the sensor outputs so that should be a pretty easy diagnostic to perform. Anything else I should try?
