350TBI
Newbie
1995 GMC C1500 350 tbi with a rebuilt 4l60e 275k- has been idling really rough in park surging and ultimately stalling after a few minutes usually with the ac off. Truck runs good when given throttle but the surging and stalling is driving me crazy I’ve tried everything. Replaced EGR valve, Map Sensor, IAC Valve, PCV Valve, TPS, vacuum lines and hoses, Distributor Cap and Rotor, Plugs and Wires, Intake Manifold Gasket, Throttle Body Gasket, Valve Cover Gaskets, Fuel Pump, Fuel Filter, all in the last month or so just tossing money at the truck. No mechanic in my area can help me out any assistance or directions would be appreciated. I love this truck and will rebuild it 20x over before getting rid of it. I appreciate any advice !
