idle problem

I have a 1992 Mazda Mx-3, 4cyl, 5 speed. The car has a problem keeping a constant idle. usually ranges from 1200rpm - 200rpm. Sometimes it doesnt do it but other times it can get really bad. I was just looking for some opinions on what could be causing that.

It may be your flex type intake tubing has some small cracks or a possible faulty coolant thermosensor. At any rate, I believe this thread will be moved by one of the moderators to the 4 cyl section.

Anticipate a move of this thread.

Thanx alot for the info

Question though. Im really not to sure how to check if those were the case of the idle problem. Im sure it would be hard to explain how to check but if someone could possibly help me out on this that would be much appreciated

as suggested by many other members in many cases like yours that i've seen (also tried by myself when I had this problem) Spray some WD-40 around your intake while running the car and if your idle spikes noticeably then there is a crack somewhere that needs to be sealed, try visually inspecting first if you like. Realize though, even cracks that you can't see with the naked eye can make a big difference when your engine begins craving and sucking air.

Not sure why some like to use WD40 since it's effectiveness must be minimal, not to mention the oily mess afterwards. Use a butane refill bottle and you'll have much better results. Use around all vaccum lines too to confirm their integrity also.

Just listing what everyone else says to use. It worked for me and I'm not the most mechanically inclined person around. I wouldn't try anything that I havn't been told works because I'd be in fear of blowing up or ruining my engine somehow. Bad luck seems to follow me around, so I stick firmly to instructions that way if something bad happens I can put the blame on someone else
