Ford f150 power loss at half throttle

Ive got a 1995 Ford F-150 4×4 with the 302 5 speed. All started with a few bucks when it was cold and the check engine light would come on then go off. Now the check engine light is steady on and it works ok at half throttle.

But anymore than that it looses power completely. The truck is shut off only its not. If you let off the gas it goes back to normal till you go above half throttle again.

Answer: You need to first get the codes scanned from the computer. Your truck might have a bad throttle position sensor (TPS).

You might have a problem with low fuel pressure. Either a bad fuel pump or plugged filter. This would loss of power at higher engine RPM and hard acceleration.

Truck may also have the ignition system cutting off. You would feel this as an engine misfire then cutting off. A bad ignition coil that is breaking down under heavy loud. Try spraying water from a squirt bottle on the ignition coil to see if it causes your Ford to start sputtering. Or you may even see spark jump from the coil to a ground.

Possible bad ground wire. As you accelerate hard the engine ill normally move. It would be even worse with a broken engine mount. The engine moving will pull on wiring harnesses. Try doing a break torque. Foot on the brake pedal firmly and give it heavy throttle. If you can get it to act up, put it in reverse and do the same thing. If the problem goes away then look for wires being pulled since the engine moving the other direction in reverse does not cause the problem.

Ford Escape Misfire

Question: I have an 09 ford escape, V6 3.0L, had a problem with a misfiring cylinder 3, checked the codes and it said injector circuit open, asked one of my mechanic buddies about it and he went to my engine with a stethoscope and told me the injector is firing just not well. I went in and replaced the injector and connected back the stuff i needed to turn the engine over and it sounded brand new, i shut it back off to finish putting everything else back onto the engine and when i went to start it up again it stalled out after about 10 seconds, rpms just got lower and lower till it died. anyone got any ideas on whats wrong with it now?

Answer: Does the engine start back up or is it no a no start condition? If it does not start at all now, check fuel pressure. If it does run but then dies out every time you start it, check for a vacuum leak. You may have knocked off a vacuum or air inlet hose to throttle body while doing the final re-assembly of everything else.
