Hey guys,
Got a 350 TBI engine in a 87 silverado. Engine worked fine before I laid her up 6 months ago.
Now she back fires up through the intake of the TBI.
Engine starts fine. Runs fine all through the rpm range while in park. Problem is when i am running along and step on the gas, it is almost like a back fire up through the intake of the TBI. not sure if i am using the correct term with "backfire" but that's all i got.
I have replaced both injectors, TB position sensor, idle air valve. And the truck still does the "backfire" through the intake of the TBI when i accelerate
