Idle Problem
 

Hi,

I have a 2000 Grand Cherokee Laredo w/ 4.7 V8. Sometimes when it is
idiling in park the engine will surge. The tach starts rising and
falling just below and just above 1,000 RPM. It doesn't do it all the
time and restarting will usually stop it for a while. I took it to the
dealer a few weeks ago and they said it was a dirty air filter. That
didn't stop it so before I spend more $$ does anyone have suggestions?
The Jeep has 68K miles.

Thanks for any help,
Brandon

Sounds like symptoms of an idle air control (IAC) valve, but it's just a
guess without testing it. Sometimes they just need a good cleaning. Maybe
someone else can confirm this for you.

Maybe the throttle position sensor?

Re: Idle Problem
 

I couldn't disagree more with the misfire advice. If there were a misfire,
engine computer would pick up on it and turn on the MIL. Engine idle speed
is controlled by the IAC for large changes, and ignition timing for small,
fine adjustments. Various inputs to the computer can cause it, including
TPS and MAF as heavy hitters.

Don't diagnose it yourself, you will spend far more money than the $75 or
whatever a good dealer shop will charge. In the hands of a good tech, this
should be a pretty simple find and fix.

Re: Idle Problem
 

Thanks for the advice!

I hade the spark plugs replaced about 1,000 miles ago so that can't be
it. Where are the IAC and TCS located? I would like to take a look at
them and try cleaning them if they aren't hard to get to.

Was that before or after the problem started? If before, it might just be
that you got a bum plug...
