1995 Buick Regal Custom 3.8
I have this really strange problem that I cant seem to figure out. Maybe someone can provide some insight to this.
I noticed a year ago that my car would randomly stall out coming into work after a 20-25 minute drive. It then started to idle really high, very rarely. So i cleaned the throtle body, new air filter, new fuel filter, sparks, and wires. This is about where my expertise ends.
Its seemed better, however, it would act up now and again (stall) but I was fine with it.
Recently I have noticed that the car idles really high 1.5 in drive (compared to 900) and 2k in park after I have drove for 20-25 mins. So I put the computer to the car and all I have is transmission error codes which I have had since I owned the car at 80,000 miles and I am now to 160,000 miles. This car has been pretty good to me because it starts, goes forward, and backwards! What else can you really ask for. A better idle maybe?
Thank you for any help you can provide.
