91 Buick Regal Stalls when Starting
Friends series1 3800=Problem sometimes when first starting cold or after sitting an hour lately, it stalls out and requires 3-4 re starts before it will run normal while applying gas. no codes or CE light. Engine seems to run good after that.
I asked him to temp use higher octane fuel, and I put a bottle of water-remover in fuel & carb/injector cleaner in new 94 oct fuel.
My guess is to start at fuel filter with replacement. May not have been replaced on this car in a while as it has about 250k miles and he has had it less that 1 year.
What about fuel pressure regulator could this be causing a problem too?
Unfortunately I was not able to remove the IAC today as it is angled on 45 degree and someone has changed one of the Phillips screws with a T-20, and I have no allen type t-20 to get in there.
Thoughts or comment appreciated..Thanks !
