And by high idle, I'm talking 2,000 rpm's. Its a '99 4.0 classic with 141k miles. Sometimes when I start it up, it will idle between 1,500 and 2,000 rmp's for a minute then drop to 800 or so. It will also do it when I put it into park or neutral after driving for bit. It doesn't always happen though. Something that ALWAYS happen is when my AC is on, it idle's at about 1,200 rpm's which i expect to be higher, but not that high. When I'm braking and coming to a stop, the rmp's will jump up to almost 2,000 rmp's lurching me forward, where I have almost rearended someone. I had the I had the IAC replaced at about 110K miles. Any idea's?
