When accelerating engine did not return to a normal level. It suppose to return to 800 rpms, instead it hung up at about 700 rpms also, it did this at highway speed. Consumer has contacted dealer, and dealer reset computer and cleaned carbon. However, problem kept returning. This was dangerous because when accelerating and taking foot off of gas pedal vehicle did not slowdown, it stayed right at that speed. Please provide any further information.

When consumer releases brakes to go foward from a stop vehicle will accelerate forward. Dealer claims this is a normal characteristic, and cannot be repaired.
Automobile accelerator stuck and would not release without shutting off engine. Vehicle stuck at 60mph out of control!!! Very dangerous and lucky it did not result in serious accident or fatality.
Consumer believes the design of the accelerator pedal on vehicle is unsafe, there is no tacticle feedback and consumer cannot tell when the engine is going to kick in until it does. Nlm
