cool. i just went under the hood and found the switch. i unplugged it and plugged it back in and i found the other one with 7 pins and loosened it up slightly as i have unplugged it and found my car idle so low to the piont it was gonna shut off. i am testing my car now (remote start is the best!) and so far so good....now if i can just pass smog and get my emissins level low....im at 128 (hc) and the max is 114....any suggestions? does that stuff you put in your gas tank help? its like the never ending battle

If your throttle/thrust/micro switch has failed, unplugging and replugging will not help. You need a new one. Do you know, for sure, whether it is this switch, or the IAC, that was the probnlem?

For emissions, Techron helps; can't comment about other additives. Just make sure there is none of it left in the tank when you get the test, or it will send your HC numbers off the chart.

High HC can be caused by of incompletely burned fuel, or piston rings that are not sealing. AutoRX will help with ring issues, but not quickly.
