truck would die before I replaced the IAC when putting into park, but the rpms still drop to and below 500 rpms when shifter into park. is there something else I should be doing?

 

did you clean the MAF sensor

 

no, I have MAF cleaner because I tried cleaning my old IAC.... is there a special way to clean the MAF sensor?

 

Is your air compressor running?

 

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.

 

your gonna need tamper proof torx bits to do this

 

for the ac? if so yes, it runs

 

Ah yes, forgot that part. Thanks.

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.

 

mine does the exact same thing

 

UPDATE

cleaned the MAF sensor and she runs beautifully now. Thanks everyone!

 

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)

 

its suppose to drop. Thats why you have IAC to bump the idle up for the ac stealing power

 

yeah 15 times per side with the straw connected to the can and air dried for 15-20, i hear your not suppose to touch the filaments in there at all...... i'm about to re install my old IAC and see if that made the difference.....i'll let you ppl know if anyone cares to know

 

i know that lol

 

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+
