TBI 350 Idle issues...again...
1994 K1500 tbi 350 280,000 miles. 8,000 on new engine
wants to lope and die at idle.
new knock sensor
tried all kinds of base timing levels
i am thinking it could be fuel pressure? (replaced pump 40,000 miles ago)
worn throttle shafts?
Some even say oil pressure switch. I replaced when i put new engine in.
i am at my wits end with this thing.
