Engine Mechanical problem
1996 Chevy Lumina 6 cyl 188000 miles
After starting car (with cold engine) the car idles fast, I usually leave the car at high idle for a couple of minutes, and the only way to slow the idle is to shut the car off, then turn it back on. If the car is ran for a while (10-15 miles) and you shut the car off for 1-2 hours the idle is normal, if the car is off for any lengh off time 8 hrs to overnight, and I start it it has high idle. The check engine light is on, a mechanic checked codes and said the egr valve is bad, but this is the only code, and did not know what would cause a high idle without alot of labor (money), he suggested just keep turing car off. This is my 16 year old daughters car, I would like this to work. Do you have any suggestions?
