Runs erratically If I have it in park with no foot on the gas pedal it will rev up and drop down to normal continuously. Driving down the highway it will lose power...almost like its coughing or can't get enough air?

The idle air valve (located below the throttle body) provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to the idle air valve. This means that the idle valve is not affected by air leaks or a jammed throttle valve.

I have a 2004 grand prix, When you are driving down the highway, and you take foot off gas, there is vibration


Hi Cheyenne:
- For the vibration, I'd be checking universal joints or CV jounts.
- Sounds like you've got your brakes figured out already. Time for some maintenance.

I would consider changing the vehicle speed sensor. When they go bad, they can really throw out a lot of bad data to the computer, resulting in unexpected behavior like you're experiencing. They're only around $20-$25. I hope this helps! :)

check your transmission fluid levels and add if low..also using a white paper towel, wipe some fluid off the stick and see if any contamination is present like blackened gunk and aluminum shavings..this is a sign that the fluid and filter need changed..

Vw polo maintains engine revs when foot is off the accelerator.


You need to check the cable the runs from the gas pedal to the engine, it might be rusty and need some drops of penetrating oil at the point it meets with the engine accelerator valve.
