I know everyone has read about a thousand idle problems, but... My car will not idle cold. It will start, run for a few seconds and stall. I can restart it and feather the gas to keep it running. It will then surge from about 500-1500 RPM, then after about 3 minutes, will idle rock solid. When first started it will also stumble like it's missing when you hit the gas. This also goes away after about 3 minutes. I have no codes, the ECT and ACT sensors read out fine when warm, I have checked for vacuum leaks everywhere and I've gone through the Probst, Ford Fuel Injection book trying to troubleshoot. O2 sensors are fairly old, but supposedly the computer doesn't look at those until they heat up. Plugs are new, ignition is new, plug wires are new and timing is set @ 14 deg. I got nothing. Any ideas? Thanks!
