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.

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.

Re: 98 Cherokee 4L I6 hesitates when cold
 

There are a couple plugs and sockets on the throttle body. Opening
these and cleaning the pins with a spray contact cleaner or even WD40
can do wonders for cold idles. One is the TPS or throttle position
sensor. Ours in an 88 and I need to clean it every couple years.

I've had some of the Bosch Platinums break down internally - no
external sign of damage. They usually would misfire only under heavy
load (slowly getting worse) and were not carboned up like you would
expect from a bad plug. Almost impossible to diagnose. At least when
the Champions fail, they fail completely so you can tell which is
which.

Hi Will,
Ditto. I'm really surprised Mike thinks they look good. They should
show obvious signs of misfire fouled:

Re: 98 Cherokee 4L I6 hesitates when cold
 

I will third this opinion on spark plugs, I would recommend a "normal"
plug. I've had good luck with normal Bosch plugs in other cars but only
had good luck with Bosch Platinums in a VW. The other times that I
personally tried them (until I wised up) I always eventually had misfire
problems. Must be my selection of vehicles:) I've always had good luck
with plain old Champions in Jeeps and other Chrysler vehicles.

Regarding hesitation when cold, I would recommend checking all the
vacuum lines. When I checked them on my '93 GC last summer a bunch of
them were hard and/or cracked. I replaced them all and my GC seemed to
run better especially right after start up.

Re: 98 Cherokee 4L I6 hesitates when cold

You talking about me? I think Bosch platinums are junk and have never
seen a Jeep engine run well on them.

The last 1 year old set I tossed in the trash for someone did show signs
of misfire though and still ran like crap when warmed up.

That is why I mentioned the TPS connection. It is more likely to give
cold running issues I would think.

Re: 98 Cherokee 4L I6 hesitates when cold
 

The plugs really do look good - nice and clean. I haven't had any
problems with them since I put them in over a year ago.

I've taken the jeep around the block a few times in the last few days
when it's cold, and it is running fine. I don't know what the deal was
the other day. If it happens again, I'll take it in. Thanks for the
replies.

The plugs really do look good - nice and clean. I haven't had any
problems with them since I put them in over a year ago.

I've taken the jeep around the block a few times in the last few days
when it's cold, and it is running fine. I don't know what the deal was
the other day. If it happens again, I'll take it in. Thanks for the
replies.
