Truck dips below 500 rpms when put into park even after replacing IAC

Pull your MAF sensor out (I think it unscrews) and spray the circuit part with the cleaner. Let it dry before putting it back in and firing your truck up.

What I meant was....

When your rpms drop, is your air compressor running? My rpms drop sometimes at a stop when my a/c is on.

How did you clean it?

Did you just spray it and let it dry?

Ive cleaned mine before, but was wondering if you did anything different (like ear swabs or anything)

ok so check that...... It still goes down but now not past 500rpms and not nearly as often. I think their was nothing wrong with my original IAC (just needed to be cleaned) and the MAF Sensor just needed to be cleaned. I'm going to drive around for a couple days w/ the original IAC and if it works the same as it does w/ the new IAC i'm returning the new one and this job will have only cost be $19 to fix instead of $90+
