Well, like many others I've been fighting idle gremlins for awhile. My motor is rebuilt about 15k ago, and no adjustments have been made since my 1k check up. Last month I installed a CAI, and since then have had pulsing idle. When AC is on its rock steady at 1k, but without it it either is steady at 1100 or pulses between 200-800.

I *painstakingly* went through everything over the last 4 weeks looking for a vac leak. Replaced a few gaskets, applied a few new hose clamps...no luck. My car is absolutely AIRTIGHT.

So. Out of frustration, I started adjusting my TPS. 1/4 turn at a time. Finally...1 full turn later, it fell into place! The thing is, I figured since all I had done was put on CAI it wouldnt be TPS. I was wrong hehe.

My motor has such good compression it holds an idle at 400 RPM, but I set it to 750 of course. Absolutely rock solid. So with those with idle gremlins, hopefully my experience can help. One thing I know after 3 RX's, they are VERY tempermental with regards to vac leaks so start there.

Hang in there...you'll get it
