Ok my car is having idle issues and I can`t seem to figure it out. I replaced the IAC reset the base idle to about 800rpm and the TPS to .98 and cleaned the MAF. Sometimes it will idle correctly. But it will usually surge from around 800-1400 and then it will start dropping lower until it dies. When driving it will die everytime I stop unless I keep giving it gas. Now as far as the mods on the car here is what I have: 347, Vic Jr heads, Systemax intake, 42lb injectors, 80mm mass air, 76mm TB, Ed Curtis cam .624 intake with 236 duration .584 exhaust with 242 duration, and a tune by Ken. It sems when I take the car to Ken it doesn`t mess up :bangwall: Any suggestions? Thanks.

Hey Ford fan, I bought and installed an Idle Air Adjustment plate from Ford Racing.(part # f2pe-9f939-aa.)

It mounts between the IAC and TB. Im not saying it will definately work for your combo but for me it WORKED LIKE A CHARM.

Best 30 dollars ive ever spent. I believe you can get it from 50 resto or ford racing.
