weird idle

[Cornfedgt]

Another mystery to me is at certain times my idle surges to 1000 then back to less than 500 and back to normal. Also under light acceleration my car chugs like it wants to die. I have no clue as to what is happening.

sounds like a vacuum leak.

ever replaced the stock throttle position sensor? Easy to test, easy to replace and not all that expensive when mine acted similar.

How do you test the TPS?

well the water outlet gasket was shot so its leaking antifreeze into my cylinder 5 spark hole. so after i figure this out i pull the wire off and use my antifreeze test tube to suck the antifreeze outta the hole and oh wow, my car is a new monster.

glad it was something easy to fix.
