Question about 1990 Ford F150

1 Answer

When I let off the gas it jerks

Every time I drive the thing when I let off the gas it jerks, not forward but in a stopping motion. The RPM gauge doesn't appear to correspond with the **** either so I don't think its anything to do with the engine. It also jerks when brake pressure is applied.

What is the vehicle specifically? Jerking when letting off during hard or mild acceleration could indicate a problem with an engine or trans mount. More severe cases its indicative of a loose, worn, damaged drive shaft or pinion. If front wheel drive car, lean toward engine mounts. But to clarify again, we need details of your situation to help more effectively.

SOURCE: 2002 Ford Explorer Jerking when in motion

Does the jerking feel like a fish bite ( especially when pulling a hill?) if so it may need plugs and wires

if you have one bad plug wire the problem seems to smooth out at higher speeds

Hope this helps

SOURCE: Electrical Problem?

For some reason you lost power. Start at the battery, checking connections, check connections on the engine block(grounds), connections at the starter. What is the repair history on the van? Is this problem intermittent? A faulty ignition switch could cause your problem.

SOURCE: jumps forward when brakes are applied at intersections when stopping Doesn't happen all the time.

I don't know if this would be considered a solution or not but in 2006 Ford implemented a new transmission (6 speed automatic) and they have and still have a lot of problems. It is fixed (helped may be more appropriate) by a computer upgrade done by the dealership. MY wife has had nothing but problems out of her 2006 limited ford explorer. The whole computer system had to be replaced at 32,000 miles and then they charged us to upgrade the new computer they put into the car. It's almost comical at this point. The transmission problem has been solved for the most part on our vehichle but it took several ford computer updates. I hope this helps!

SOURCE: 2001 ford focus jerks when gas applied while

Safely, take your car on a highway or street ( dry pavement ) with no cars or other persons around. Stop the car,proceed to approx. 20 Km/h. Then push the gas pedal down close to the floor, if the car bucks and chucks change the fuel filter and retest. If the problem is still present, I recommend the fuel pump. Have it checked first.
Please rate this.

This is a rare one and can be tricky. Since your rpm gauge rises back up when you increase your acceleration slightly but you feel no jerking of acceleration then this tells me that a speed/rpm senser either has a bad connecton or the sensor itself is going bad when the engine reaches an optimum heat while driveing on the highway. Since you feel no acceleration when you slightly press the accelerator down but yet the rpm gauge is increasing back to normal, the throttle body sensor may be compensating for the failed speed sensor/failed sensor connector. Please get your uplander diagnosed properly first to confim this.

Have the fuel pressure checked- this would determine if your fuel pump is working properly. Its really easy if you have a gauge. you might be able to rent one at a part store. or it could need a new fuel filter
