For the MAF, you can go to the part stores and buy a MAF specific cleaner (follow the instructions and you're golden).

For the IAC, I've used carb cleaner and q-tips/paper towels. Keep in mind, you not just need to clean the IAC, but you also need to clean the inside of the port on the throttle body where it sits.

 

Seafoam DeepCreep is pretty good for cleaning the throttle body out. Just don't touch the MAF with anything but specific MAF cleaner.

 

Yea, I heard about that. But thank you guys again.

 

No problem! Also remember to disconnect the negative terminal before touching anything

 

gotcha!

 

hi my car is having the same problem the shop that I took it to replaced the iac but the car keeps shutting off what could be the problem

 

same here. replaced IAC, MAF 2 times, o2 sensors, spark plugs, coil packs, upper intake, new air filter, new fuel filter, cleaned the throttle body and still when its warmed up it it dies in idle unpredictably, and surges when im going under around 50, and when its still warmed up and i try starting it again will start and then die. HELP?

 

Check your Cat! mine was clogged/bad and did this same crap, replaced and fixed issues!!

 

Cat isn't glowing red or smelling like rotten eggs so idk if it's that, that is bad. Anyone?

 

They make MAF cleaner...
Is your MAF an AC Delco? If not...
I highly recommend using only AC Delco.
Do not touch the filament in the MAF..merely spray it clean, let air dry.
Do not wipe it out/off..

You can use carb cleaner to cleanout the IAC (Idle Air Control)


It may also be the TPS..
with the grease that's in it could be freezeing up and or needs to be cleaned and regreased. possibly.. It maybe sticking..

IMO:
K&N cold aire intakes cause more problems then there worth,
Via over oiling and or loss of particles from the filter.. attaching themselves to the MAF..

Your not the first to have problems with using a K&N filter system.
We highly recommend using one from CAI Inductions.
