Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
That's the thinking. The theory is that your IAC has carbon in it, which is
making it function improperly, which is what is messing with your idle
speed. Cleaning the contacts for the various sensors mentioned can help
too.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
This is probably a really dumb question, but how do you remove the linkages
from the throttle body? Some of the posts I've seen indicate it may just be
a simple ball/socket joint, which means I just didn't use a big enough
hammer (figuratively speaking, of course) on it. Thought I'd check in here
first, though.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
This is probably a really dumb question, but how do you remove the linkages
from the throttle body? Some of the posts I've seen indicate it may just be
a simple ball/socket joint, which means I just didn't use a big enough
hammer (figuratively speaking, of course) on it. Thought I'd check in here
first, though.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
You are correct about looking for a vacuum line loose.
The CCV, if pulled off at the manifold will cause a steady high idle,
but normally it gets blocked which just pukes oil into the air filter.
It would be worth inspecting the rubber grommet where it enters the
manifold for cracks though.
