At one point i thought it could be air in the throttle plate but it sounds like its comming from the back by the distributer i changed one 3/8 hose that goes to a valve unit on the firewall..no change...
there are 2 wires at the IAC do you know the voltegs that i should look for and if it was shorted would the car run as good as it does...and would it allow me to go for a 20 minuet ride
without throwing a CEL....when i got back i shut the car off then restarted it and it threw a CEL ???
thanks I need all the help i can get..
