The gas pedal could beva drive by wire, meaning there is no physical connection between it and the engine. You did not say the year of your Envoy. If it is there may be a bad accelerator position sensor. If is not drive by wire you may have an issue with your engine. Either way have it checked by a technician that knows you make of vehicle.

I HAVE A 2004 AZTEK AND HAVE VIBRATION WHEN PRESSING GAS PEDAL. WHAT CAUSES THIS?


you don't say where the noise is. that is important to give a clue where the issue is. when stopping on the brakes 3 things happen. you press the pedal and the abs pump starts pumping fluid. the second is the brake capilers start pushing on the rotors to slow the car. the rotors are attached to the wheels and that stops the car. so if the rotors are warped you will feel a vibration in the steering wheel when stepping on the brakes. if its your foot feeling the pump working that is normal for abs pumping. you should feel it and holding the pedal will keep it working and stop you from skidding if everything is working correctly

I have a 2007 ford F150 XLT 4X4 flex fuel 5.4L. The truck just developed a vibration once you pass 70km an hour. If you let off the pedal it stops. If the truck is on cruise control its minor until you...


Thats a good one. Going by what you are saying the vehicle has to under a load in order for the vibration to occur. Best guess would be rear end or torque convertor.

The whole front of my expedition vibrates when i push on the gas


it can be a motor mount. when the vibration occurs shift into N and then if it stops then it is your transmission. it could also be loose lug nuts, a bad wheel bearing, tie rod. or something else in the suspension.

Our S80 Vovlo, as the vehicle is ruuning, I hear a air leakcoming from the brake patel area, as I touch the patel the noises stop and as I let out the brake patel, the air leake strat again, have any


it sounds like the vacuum pipe to the break servo is leaking or it could be the servo diaphragm broken hence you hear the noise in the car, if the brakes are harder to press its most likely to be the servo unit more than the pipe i would also expect you to having a ideling problem due to the extra air in the intake system. hope this helps regards John
