Idle Problems

[Customs222]

I've been noticing the past few days (they have been very cold!) that my idle has been acting strange. The car is an automatic and idles around 600-800 RPM in park. Every three to four minutes it drops to around 200 RPM and sounds like, and gives a quick jerk, like it's stalling, then returns to the normal 600-800 RPM range. Anyone experience this or have any clue whats up with it? Thanks

Yeah check my other threads on this. Just search my name or search for Strange Idle. I have posted alot on this topic and just to let you know my car is going back to the dealer for the final time to have a Mazda tech from Corporate look at it and that is the deciding factor for the Lemon Law.

warm the car up and disconnect the iac valve and check ur idle speed it should be at 750 i believe for auto.
