HI,

I have a 93 mazda mx-3 with the 1.6 liter manual trans. I just bought the car a few weeks ago and I have had to replace the oil pump, and the head gasket. The car runs great on cold startup but once it warms up to operating temp the idle keeps flucuating from about 300 rpm up to 1100. It runs fine above idle. I am just getting tired of working on this thing. Any help would be greatly appreciated. Thanks.
