98 Cherokee 4L I6 hesitates when cold
Anybody have any idea what to check on my 98 Cherokee, 4L I6, 105k
miles? Symptoms: hesitates, especially at low speed (5-20 mph).
Sometimes does the herky-jerky in idle right after starting. Symptoms
seem to go away at higher speed or when engine is warm. I'm in Utah, so
it's below freezing most of the time right now.
Thanks,
Mike

Could be any number of things, failing coil, cracked plug, bad plug wires
(If your model still has them). Clogged fuel filter, failing CPS sensor, etc.
Pull the codes and see if it's got anything in there.

Re: 98 Cherokee 4L I6 hesitates when cold
We had a brand new cherokee (4.0L) in 2001 that had a rough idle first thing
in the morning. Seems to just be a characteristic. I had the stealership
look at it a couple of times (even had a plug go bad on me at about 15k
miles). My 2000 we have now does the same thing when it's cold. Doesn't
seem to be anything wrong, just a not-so-refined motor. Works like a charm.

Re: 98 Cherokee 4L I6 hesitates when cold
Thanks for the replies. I pulled the plugs out last night just to
check (Bosch Platinums) and they look fine. After reading that some
people didn't like them, I considered switching, but they look great
and they've been fine for over a year. I'll see how it runs for a day
or two, and if it doesn't go away, I guess I'll take it in. I'm no
mechanic.
