Re: Need advice on 97 TJ.
I have had a similar problem to the OP ever since I bought my 97 TJ a
year and a half ago. I have a standard, (so this has nothing to do
with shifting; I would know that), and sometimes, especially if it's
cold out, it will hesitate when starting from a stop sign or stoplight
in the morning. I'll give it gas, it will act like its going to go
normally, hesitate a moment, then resume normal acceleration speed. (I
don't get the "jerk" the OP described, though...) I have yet to figure
out the cause of this problem, but haven't put much effort into it,
either. I figured at first my fuel pump might be dying, but after a
year and a half, I would have thought it would be fully dead by now,
were that the case. I do seem to recall an error involving my MAP
sensor being detected on one of AutoZone's little error code readers
when my check engine light was on after high-altitude 4wheeling this
summer, though. Could this be related (since someone mentioned the TPS
possibly being related, I started wondering about this other sensor
also maybe having an effect)? I haven't replaced the MAP sensor, yet,
though, because it didn't seem that big a deal to me at the time, and
it was kinda pricey.
Sorry, I don't have any help for the OP, but if someone comes up with
a good reason this could be happening that could help both of us,
that'd be great ;-)

Re: Need advice on 97 TJ.
A guess would be the Throttle Position sensor, needs to be cleaned
or replaced.
