Here's a weird one - can you guess what it was?

#21

Would have bet on a broken engine mount, but seeing where this is
headed, I'll put my money on a loose throttle cable connection on the
engine side.

Nope, that was my first thought but not the problem. (And if I started

Some bent lever on the throttle body.

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!

Anyway, the Jeeps 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.

Well, of course I knew that*, I was waiting for you to tell us you were
giving a new Grand Cherokee Limited 4x4 V8 to the first correct guess.
You might as well go ahead and send me the GC anyway.....

*If you believe that, I also have access to several million US dollars
stashed in a Nigerian bank and you can help me bring the money to this
country for a 15% cut! <GD&R>

I'll have the Grand Cherokee delivered as soon as the money from Nigeria
arrives <G>

No doubt put there by rodents.

I want part credit!

Just FYI, but that air filter is to filter air going 'into' the valve
cover....

I would be checking out the CCV system expecting to find a blocked tube
from the rear of the valve cover to the intake. This is the other half
of the circuit that is supposed to provide the suction for this.
