Need advice on 97 TJ.
 

Hi folks. I have a 97 TJ auto with 69K miles. I notice that whenever I
leave the jeep overnight or few hours under very cold condition, the
jeep will hesitate after a few minutes of driving. I could be driving
up few blocks, stop at the stop sign, when press on the gas, the jeep
will not move (for a second) and then after a jerk motion, the jeep will
move again. Once that happen, it will not occur again. This can even
happen when I was driving (25 mph) and all the sudden feel the jeep is
not responding to acceleration but after a second or so, the jerk motion
and everything is fine. The tough part is that once it happen I can't
duplicate on the same day. I took it to the dealer and they told me to
bring it back when it happens more often. Any idea? Thanks in advance.

Re: Need advice on 97 TJ.
 

We had similar symptoms along with a bit high a rev on start up. Just
the one hesitation and sometimes a stall at the first stop in the cold.

The connection on our TPS was dirty. I sprayed it out with a contact
cleaner like WD40 and it worked perfect for 2 years. I had to do it
again last summer.

Just pull all the connectors on the throttle body and spray clean them.
It is a good thing to do now and then anyway on a Jeep, water and mud
have this way of getting in strange places.... ;-)

Sounds like you might be low on transmission fluid.
