Default 2001 Buick Regal stalls when coming to a stop
Stalls randomly, sometimes right after I start driving. Other times it takes a while for it to happen.
Replaced the map sensor, air filter and the idle air control valve. P0442 code was on the scanner.

P0442 is a small leak in the EVAP system. Probably not related. I agree with carfixer007 ^^^^^^^ that cleaning the TB is a great place to start.

No I haven’t, seems pretty easy to do though. I’ll give it a try in the next few days and report back.
