Engine Performance problem
1992 Ford F-150 V8 Two Wheel Drive Automatic 200xxx miles
I have a 92 F150 with a V8 5.0, and I have been having problems with it for quite a while. It is pretty hard to start once it sits for a while, it cranks over but wont start. I have to crank it for a while, like 4 or 5 cranks. Then starts up, when put in gear and I step on gas it turns off. It'll start right up, but run poorly. It'll jerk and buck during acceleration until I really mash down on the pedal. And as the engine warms up or more fuel is passed threw the system, it slowly goes away. If the engine is warm or has been driven for a while, the truck is easy to start and wont really jerk or buck at all. Ive replaced, Throttle Position Sensor, Mass Air Flow Sensor, Idle Air Control Valve, and replaces all of the tubes that pass air to the Manifold. What else can be the problem?
have the same problem?
