In NJ, The idle upon starting the car would rev high then go down for a about 3-4 minutes then smooth out. Since Buick says that this model year the idle can’t be adjusted, I’m trying to figure out problem. Now in FL, the car starts up fine, but after driving the car maybe 5 miles then stop the car stalled going into parking space. Also, after an hour I start the car and starts to idle rough to the point that it wants to stall. I want to get dirty as soon a get the right battle plan together to fix the performance issues. She only has 77,000 miles on her.

I would search for vacuum leaks.any unmetered
air will cause idle problems. also clean the
throttle body. check your IAC.turn your ac on
your car should idle up.if not.Try cleaning the
IAC and inside ports.Also check your throttle cale
is not to loose.I definitely was leaning in those directions, college man. I did find the rubber duct to the throttle body loose and tightened it, but I do strongly feel as well that the IAC has a lot to do with that up and down idle, yet I think cleaning the throttle body will also help. Eric should make a video on working on Buicks because I have not found any videos on any Buicks. Now I can get dirty! Thanks, College man.
