      My 93 wont stay running whenever the temp drops below freezing (approximately) It will start fine but it stumbles and dies. Once it has warmed up it goes away and it never happens in the warmer months. Within the past year I have replaced the thermostat, pcv valve, cleand iac and maf. Could it be the iac freezing up and sticking?

      Could it be water in the fuel? That can cause a lot of problems in cold weather... Try running a bottle or two of ISO-Heat (any isppropyl alcohol water remover product) through the fuel lines - and also changing out your fuel filter to see if that makes a difference before moving on to other, more expensive issues.

      Also, if you suspect the IAC of sticking, that can be removed and cleaned with carb cleaner. That will generally cure it from sticking.

      I don't think it would be the filter or water in the fule because once it is warmed up it runs fine. I am beginning to think that it is the iac because it has done this before in wet weather.

      Just for kicks, try spraying all your spark plug wires with WD-40 next time it is wet out... If it helps, replace the wires - they may be letting in moisture.

      (That is what WD-40 is best for - drying out spark plug wires! - works great when you get the underhood area packed with snow or drenched with water from a deep crossing)
