The Jeeps (96 Cherokee, 4.0) been acting strangely lately, sometimes it seems like its down on power, the gas pedal has felt hard, and the idle has been weird, sometimes slow, (especially at startup, even with the engine hot)and sometimes fast, like about 1200 rpm.
I couldn't believe it when I found the problem, and it was an easy fix.
Any ideas?
Answer to be posted tomorrow or so, unless someone gets it first.

Carpeting/insulation? Jeff
Nope!
I drive the piss out of this Jeep, it hardly sits still long enough for any critters to get any ideas.

Bad ground. Current frayed throttle cable?
That's what I was thinking, but no, the cable and spring are fine.

Funny you should mention a bad ground. Once in while the gages get all wacky and it's because of a ground connection on the engine, but it's never effected the way the engine ran.
Not a ground, not a bad throttle cable.

No cruise, it's a very basic Jeep.

OK everyone, there were a lot of really good guesses (and most of them have happened to me at one time or another!)but here is what happened this time.
I took the big air intake hose off the top of the throttle body to spray some cleaner on it and found a big, square chunk of foam on top of the throttle plates. It turned out to be the filter from the inside of the air box that filters air coming back from the valve cover.
Obviously it was interfering with the movement of the throttle plate.
A bit of cleaning and some glue and everything was OK again.
Thanks for all the great suggestions though!

PCV supply filter, usually held in place by a big staple, only time I have seen these blown out (it's PCV suction side filter) is with blowby, do you have high miles?
