2003 Dodge Neon. Driving home today and it accelerated really high without pressing gas pedal, and i can't stop it except to jam on the brakes. . Tried "jiggling" gas peddle thinking may have stuck. No. By the time I got home it was backfiring. Turn it off, start it again and VROOOOOOOOOOOOm.. Can't drive it all. Any idea?
thanks Chryslerguy!! you were right on the Neon. I really was beside myself after replacing all the engien mounts last month, then a new radiator Friday and the car breaks down again Sunday! you were correct. My brother came down , found the intake house off and repaired it! Saved me money!! thanks!thanks Chryslerguy!! you were right on the Neon.

Look under the hood for a big vacuum leak. Usually a large hose on the intake manifold near the front pops off. A big vacuum leak can cause a high idle. Hope this helps.

If you have an overdrive transmission the direct drive clutch may not be releasing. Have the trouble codes read to see if the computer or a sensor is starting to fail.
Sounds like your TPS is receiving full resistance. If cable type check cable and the lever on the throttle body, if fly by wire then it may need a new TPS
Put the car in neutral, set the parking brake, open the hood, get someone to listen/see where the sound is coming from, as you press on the accelerator.
