IAC and carb cleaner?

is there any reason not to use carb cleaner on my iac? I don't have any tb cleaner and I've seen posts of people saying don't carb cleaner. If its a bad idea then what is a better alternative?

Yeah most will say not to use carb cleaner, somethin to do with teflon on the intake... And somethin about messin up the o2 sensors. I did it however. Worked pretty good, no more rough idle! Been almost a month, No problems yet. I'll prolly get flamed for it...

I'll put my head on the block too... I've used it (against the advice of many) and had no problem. Just be VERY VERY careful on the sensor. Just an FYI - since you've got it open anyway, take the time, un-do the four bolts and take your throttlebody off to clean it properly as well. Dont just spray cleaner in the idle air intake. You'll be amazed at how dirty the inside of your throttle body can get. Plus, thats like an extra three or four beers worth of time in the garage!

There is nothing wrong with using carb cleaner on the IAC. It will not affect the O2 sensors. Some throttle bodies are teflon coated to help keep deposits from forming. I do not think any Jeep TBs are. In cases where TB is teflon coated, they make TB cleaner spray.

There's no teflon in the TJ throttle bodies. The reason I won't use carb cleaner is that they aren't really designed for engines with 02 sensors so not many of them are designed to be "sensor safe" like throttle body cleaners are.

Too bad all carb cleaners aren't sensor safe like those you found that are.

thanks guys. Appreciate the info. The bottle of carb cleaner I used said sensor safe on the front of it so that's what I used. I also made sure to try to dry up as much as possible with a rag.
thanks again.

is that what the TB is sitting on top of?...what if you sprayed in there(cause there was a bunch of coated on oil....)and mopped it all back up again? could that cause sporatic occasional chugging?
