I have a low idle problem on my other Contour when cold. Only when I put it in drive. It will almost die and then the idle comes up to speed. Once the engine warms up no problems.....I am starting to suspect throttle idle sensor but this is just a guess on my part.
IAC changed
ECT Changed
egr solenoid changed
vacuum harness replaced.
ignition pack replaced
wires and plugs replaced
