Hey guys,
Just a little update, I found what I think is a cracked gasket on the IAC housing unit that attaches to the TB...Someone told me if I spray brake cleaner fluid on the area where I think the leak is and it changes the idle of the engine, that's probably my problem? Any thoughts?

that leak is not helping any, thats for sure. sealing up that leak might be all you need to do. cant hurt.

Ok guys, just a quick question. I am replacing the gasket on the housing for the IAC that attaches to the throttle body, I bought a gasket pack for it, comes with 4 sheets, but they are all for different things tho. One is for " air cleaner, one is for "oil and coolant", one for "water pump" and the last is for "fuel pump". I know this sounds stupid but I'm not sure which one would be best, I am thinking the air cleaner one. I also got the gasket in tube stuff ( high heat rated). Which one is better?

doesnt sound like your gasket pack includes the IAC gasket. the gasket in a tube (RTV) can be used. but there are some RTVs that are approved for use with sensors, you might look into. not sure if high temp red is approved for sensors.

It's not for the sensor itself, it's for the sensor housing that bolts onto the T body, the IAC plugs into the backside of the housing and then the housing bolts onto the left side of the T body ( looking from the grill at the engine)

i would still be cautious of using an RTV that isnt sensor safe. the IAC and TPS are both very close.

The idle air control module at the top of the pic, that housing gasket right there is what I need to fix I think...hopefully it will stop the bad idle

i would assume the air cleaner one would suffice.

I would assume the gaskets are heat rated right? I feel like an idiot asking some of these questions lol

yes, they should do just fine.

i wouldnt use generic ones to seal the exhaust, but for the intake they should be fine.

ah....guys..the iac is an "O" ring. Thats what seals the iac to the throttle body. Not a paper gasket. The "O" ring is the "gasket". Secondly, you say the dealership said you have a "lean" code? Lean codes are caused by a few things, mostly a vacuum leak. I would not doubt that you have an intake leak. That would cause a crappy idle. In any event, take a can of NON FLAMMABLE BRAKE cleaner, and spray down your intake manifold where it meets the head.. ANY change in idle means a leak... period. Be it a bad manifold gasket or cracked manifold......

I know the iac is a ring gasket... I am talking about the housing that connects directly into the T body, not the iac connection part. and also the car is not throwing any codes what so ever...just that it is running lean as per the comp at chrysler. Thanks for the tip tho, keep them coming
