I have a 94 Chevy s10. Engine just started idleing up high. I placed b12 Chemtool (however its spelled) to clean out the gas. But its still running high. My question is, could this be because My clutch may be going out? If not, what else can i do to fix the high idleing.

 

Howdy, If your still having problems since 7/12/06 The the (tps)throttle positonsensor seems to be bad by your description.
