Well, Just got the car back from the mechanic and the head gasket was replace, head was resurfaced. Now the high idle is back. The car runs and drives great, but when the A/C is turned on the the engine slowly idles down then gradualy dies. Or it will slowly idle down and die when you put it in gear. Without the A/C on, it runs good just idles about 1500 and sometimes 1000. The mechanic said it needs to go to Mazda to have the timing and idel set together. He said it takes a special instrument to plug in and dial in the timing and idle together. He showed me a picture of a device that had a square box with a dial at the bottom and two leads coming from each end. Is this correct? What I don't understand is before the car's head gasket went (or when it was seaping) it ran fine with the A/C on I just noticed a little idle fluctuation. This same mechanic set the timing before and that fixed the idle. Now he's saying it take a special to to set both.
