I'm having problems with my '94 Escort
My '94 escort is having some engine problems. The engine is standard transmission. It runs fine when it is cold. As it is warming up, the engine will speed up and slow down. It only does this when idling, either in gear or in neutral. While actually in motion, it runs fine. Once it has warmed up, another problem begins. Only when the a/c is on, the engine will kill if the rpm's are low--around 1000. This happens when slowing down for traffic or actually stopping. If the a/c is turned off in time, killing of the engine can be avoided. What part or parts might be affecting this? This problem has been intermitent for about a year now, but seems to be occurring more often now. I'd greatly appreciate any help you could give me.
