Re: '90 Ciera SL - Surging idle, then dies, if left idling long enough
Ever get it figured out?
I'm chasing a fuel delivery problem as well. When I'm in the stalling mode it dies with extra throttle. I see very rusty metal lines feeding a coffee can sized canister behind the rear wheel on the driver's side. Maybe this has return fuel and is blocked.
My 91 Cutlass with the 3.1 VP holds 43 psi after cranking to 46. When I start the motor it drops to 36. Stabbing the acclerator will make it jump to 46 or so. If this has a vacuum regulator my drop to 36 may be normal. I don't know if it does have a vacuum regulator though.
There was a happy ending at the post titled 91 Cutlass Ciera not starting - no fuel getting thru injectors?.
Apparently he pulled on injector plug after another and found that with one bad one disconnected the car would start and would stall when it was reconnected
