I was driving at about 35 to 40 mph when the vehicle began to feel like it was running out of gas. It began to strain and stalling. I got it home (just barely) and parked it. A few hours later I got back in tried to start it. The vehicle fired up but idle a little rough. I put it in drive and it stays on but if I apply even the lightest touch to the gas pedal it stalled out. The idle is high in Drive and reverse but not in neutral or park. When I put the vehicle in reverse and it slams pretty hard. I have done a lot of work to this vehicle and the symptoms have gotten a little better the vehicle still stalls. I changed the fuel pump and cleared the line between fule pump and inline fuel filter with an air compressor. Cleared the line between the fuel filter and throttle body. Replaced the fuel filter. I replaced the Throttle Position Sensor, Air idle control sensor, EGR valve. I have checked over all the vacuum lines and air cleaner. I replaced fuel pressure regulator. I replaced the Distributor and it came complete. Cap, Rotor, Spark plugs. The TBI injection system is spraying a even and strong cone of fuel. I have checked the timing and had a mechanic check the timing and it is correct. Any help with this one is appreciated I am at my wits end.

This can be caused by a number of things. The coolant temp sensor could be telling the computer that the engine is colder than it actually is. The engine could be running too cool (thermostat missing, stuck open). Gasket between the throttle body/intake leaking, sucking air. MAP sensor could be seeing a drop in intake manifold vacuum or is defective or a poor vacuum source to it. A scanner would be very helpful. Seeing what the computer is 'seeing'. The TBI system uses an IAC (idle air control) solenoid to control idle speed. These can/do get dirty and sticky. It can be removed very easily, and cleaned.

I am gonna looking that cooling. Sorry I thought I put down that I replaced the IAC but I missed is in the long list. I have replaced the IAC. A scan tool would make it easier but can seem to find anyone in my area who carries one for 89's.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
