My 1988 Comanche Renix 4.0 has had a very low and rough idle for awhile now, then it started dieing at stoplights so time to clean!
This is actually a very easy job to do and as long as you have a set of Torx bits (As a Jeep owner you do have a set... right?) it only costs the price of a can of carb cleaner.
First, remove the breather tube.
It's the black slinky looking thing.

Next unhook the wiring, three plugs and done.
Now remove the entire throttle body, three Torx bolts and it's off.

I cleaned them with a tooth brush and carb cleaner, did a good job.
Throttle body after.

Don't forget to clean where the IAC lives.

After cleaning up everything, put it back together.

Success!
Love when a project works the way it should.
The Comanche went from idling around 300 to 400 RPM and dieing to this!

Well worth the hour or so it takes!
