Cherokee's problems

[JKane29365]

I was wondering what exactly is the problem with older Cherokee's. I saw
something on T.V. about a voluntary recall. I think it said that jeep was
fixing something on the jeeps but I did not know what or why they were
doing it. I own an 86' and I am concerned.

What you probably saw was a recall concerning ABS systems. It seems
that for a few years a push rod was out of allignment causing abnormal
ware. If your Jeep is equiped with this defective part you will be
notified.
I received the literature but am not having any problems so did not
respond. I simply filed the papers away for future referance as they
are good forever ( or as long as they make Jeeps ).

The 1986's did not have ABS as an option, so the original poster
has nothing to worry about. :)

If I'm not mistaken the volentary recall is in regards to a saftey feature
provided on new Cherokees and not on the old. This feature is Brake /
Shifter interlock that would not allow you to move the shifter from Park
unless your Brake is applied. All of this stemmed from several accounts of
a run away condition occuring more often than not to Cherokees and Grand
Cherokees. I'm not sure of the numbers but people were injured, some
killed, and plenty of property damage. Chrysler had a spokes person on the
show and claimed that in all cases it was attributed operator error. They
concluded that because the transmission tunnel is so large it displaced the
brake and gas pedals enough to give them a shadow of a doubt, and that in a
couple of the cases the driver was new to the vehicle hence they use this
thread to weave their web.
I on the hand have a different opinion. I own a '89 Cherokee Laredo 4.0 L
and have had a condition for the past 2 - 3 years of a high idle at start
up. The motor would rev to roughly 2700-3000 rpm and stay there with No
Throttle applied. The problem was intermittent until the Prime Time Live
show at which point it rose to a record high occurance of about 3 to 6
times a day. Finally I think I found some thing solid, on the intake
manifold to the front of the throttle body there are 2 liquid tight molex
connectors. The 2 connectors are attached to, a servo motor for air \ fuel
mixture, and the other, you guessed it, the TPS (Thottle Positioning
Sensor). On the wiring harness side of connectors are 7, maybe 8
insulated but not jacketed wires. Jeep in my case opted to route these
wire over the top of a heat isolation plate that is mounted directly to the
intake manifold. I don't know how familiar you are with this engine but the
intake and exhaust are mounted in an alternating sequence, in other words
this plate gets plenty hot, hot enough to melt insulation over time. Any
way to make a long story even longer I rerouted these 2 and only these 2
connectors over the top of a vacuum line (non-metallic). I haven't had a
high idle condition since.

My conclusion is this, perhaps the operator was unaware of speed at which
their motor was turning and poped it into gear the jolt startled them and
possibly 'Yes' they may have stepped on the gas, or at 2700 - 3000 rpm your
going to need both feet on the brakes to stop the beast. .

Your Jeep sounds like an older model and may not exhibit the same problem.
I have 2 fiends and both have pre 86 Cherokees and have never had anything
like this..

At any rate here is yet another view point at this perplexing topic.
