Hello, a few days ago my car started this erratic idling....it revs by itself. This occurs when its in park and when i am driving. I have a Mistubishi Galant 95...does anyone know what the problem might be?

Answer
Tapiwa: It could be one of many things but I will give you some ideas. Could be from a bad plug, your timing could be off or you could have a weak or have a sensor out. They control things in your engine. In that they report things back to the computer, so when they get old and tired; things get mixed up or reported wrong. And so what the computer believe is not right. Or your computer could be dying, would you have some place like AutoZone as they will check your sensors for free and give you a read out to what codes are showing as bad. Hope this helps and good luck.
