I have 2 - 1995 v6 & 1 - 2000 v6. All 3 of them accelerate when you put them in reverse. By accelerate, i mean you have to hold down the brakes hard to slow them down. I have had them to 2 different mechanics and neither of them changed them one bit. They tried different things that ultimately cost me money by did absolutely nothing. Does anyone on this planet know what is causing this. Surely someone knows what is going on. Please HELP!!!!!!

 

Could be the TPS or a vacuum leak. Just tossing out my first thought guesses. But just in reverse is strange. Probably because reverse is a lower gear than even first.

 

it actually does it in Reverse and drive.

 

Do you live on a hill?

 

What are your RPM's in reverse and drive at idle?
