This should be an easy question :). 2002 Wrangler, 4.0L. It's got over 100k and I would like to remove the throttle body to clean the IAC and the throttle body since it's been having some idling issues lately.

What is the proper way to disconnect the throttle cable from the throttle body? Does it just pop off? It looks like the fitting at the end of the cable is just plastic, so I don't want to break it.

Thanks.

Yes the connector that holds the cable connector to the throttle lever just pops off. But there's no need to remove the TB to clean it and its IAC as thoroughly as you could do with it off. I clean TBs of all four of my vehicles without removing them and the IAC simply unscrews from the TB so getting that out to clean it is easy too.

I don't like to remove the throttle body screws any more than I have to as they thread into aluminum which isn't exactly the hardest material around. :)

Thanks for the help.

I'll have to take another look at the IAC, but it looked to me like the bottom screws would be difficult to get to without removing the whole throttle body.

Does anyone have a pic of where the iac is located in the throttle body? How often should I clean all of this to because I've noticed a little ruff idle also and it's only got 48k on it

I never pull mine off to clean it, I think it actually cleans better while the vehicle is running as it allows the cleaner to mist through the air circuit, the added velocity to the spray increases the cleaning.

I've done it both ways. When you take the throttle body off you can clean it much better. Sometimes the screws for the IAC are a pain to remove with it on. You can also clean the housing the IAC is in with it off. If you pull the IAC housing be careful with its gasket. It only 4 bolts and takes 3 mins to pull off.

DO NOT, again DO NOT run the engine without air filter because its can backfire and cause injury.
