Whats up everyone!

Got a quick random question regarding the tps.


Most people say the tps should be set around .5 volts, and the range is .36-.55 or something close to that right.

Well, with my throttle stop screw JUST making contact to the throttle plate the most (highest) the tps can be set at is .45. (which is correct, i know)

BUT, inorder for me to increase the tps volts, the throttle stop screw has to be turned in, and when this happens it raises the idle around 1000 rpms and up.

So how are some people running .5+ volts and maintaining a good idle?

Just a random question, so any thoughts or explanations of the the tps or how it works are welcome!

later all!

It won't make too much of difference in that voltage range, obviously the higher the voltage the richer its going to run which makes it idle higher, just adjust ur idle screw on iac to adjust ur idle, make sure u adjust ur idle with the tps disconnected and then plug it back in when ur done
