Both my 2000 Ford explorer and my 2000 Ford taurus want to idle at 500 rpm's Does anyone think this has something to do with the Iac valve? Or is it that I still have the original plugs and wires on both and they both have over 70,000 miles

iac valves are common for the explorers.

in the throttle plate there is a bypass line that takes small amounts of gas so that a car will get gas when idling, this could be a clogged bypass line

How do you fix a clogged throttle bypass line?

sorry to tell ya but its time for a tune up buddy :licka:

original plugs and wires. I hope you,ve changed your oil. check your air filter too. :jump3:

all this stuff is simply inexpensive stuff that can cause a drastic change for your engine if it has been a long time.

also might wanna check your pcv valve if your havent been keeping maintenence on your exploder.

good luck :icon16:

sorry but it was the IAC valve hanging up found out by just tapping on it when it idled low and it reved right back to 1000. So I cleaned it and its been fine ever since
