91 just came back from the dealeship after a 750.00 tune up, it is running okay, but "idle' is so low it dies at stop lights or when shifting into reverse in a parking lot.

Is their something simple i can check or adjust myself.

Help>>>>>>>>>>>

 

does it do it right at start up? Sounds like you need to go get your money back...

 

Did you ask them why the idle is low? how low is it?
