#3887 of 5134 Engine Miss 2002 Jeep Grand Cherokee Laredo, Inline 6 by streif

Jan 02, 2008 (5:07 pm)

I replaced the spark plugs on my jeep this past weekend for routine maintenance. I immediately began having a miss. I tried everything from taking out and putting back in all the spark plugs, replacing one plug because it looked a little burnt, and I am about to begin replacing the boots. I heard the coils were expensive so replacing these is my last resort. Along with the miss, since I replaced the spark plugs I get an awful shock every time I get out of my Jeep, my passengers get it too. The engine did not miss before and I did not get the shock before.
 
Any idea what I might have done wrong to cause this to happen and is there an inexpensive way to fix it right?

I had the same problem. Thank God I purchased the extended warranty. I had about 47,000 miles when it happened to me

I own a 2001 JGC and the heated seats do not work. Purchased the extended warranty but the heated seats are not covered by the warranty. Go figure!

Technically it is supposed to have a cat on it. However, they are not necessary for the engine to function properly. I took the cat off my 98 Ram not long after I bought it. Taking the cat off increases air flow and results in greater power. The check engine light only came on once for the O2 sensor, used a scan tool to remove the code and its never come on again. My truck actually gets better mileage with the cat gone. I plan to do the same to my 98 Grand Cherokee Limited when we need to replace the exhaust. Luckily we live in a state that doesn't require cat's.

Federal law requires catalytic converters; your state may not check emissions but you're still risking fines and impoundment when they catch you. (link)
 
Not to mention that your perceived hp gain or mpg is probably minimal at best and you may in fact lose power and have worse mpg removing your cat (link).

you always have power at front wheels on your vechicle. do not use 4 low to drive in like you said it is only rated for like 8 mph. also the jeep when on slippery conditions when you turn the wheel iyll feel like its binding up this is also common

#3894 of 5134 96 Jeep Grand Cherokee starting problems... by lsufan1

This problem has come and gone over the past few months and it's back so I figure I'd try and find out how to fix it while it was acting up. But what happens is, 1, my battery doesn't hold a charge in cold weather. The battery is about a year old. Is it possible I may just have a bad cell? The alternator is new. 2, when I start it it dies immediately. It'll stay running but once I take my foot off the gas it'll die. Sometimes though it will run but idle low and sometimes die when I come to a stop. I thought maybe i could be the throttle position sensor so I put a new one in but that obviously wasn't the problem. If anyone has any idea I would really appreciate some advice.

Sorry for the long reply, my internet wasn't working. You better get a cat on it before the emissions check (unless you live in a state that doesn't have checks) but still recommend that you get it done for the environment.

Did you buy the Chrysler ext warranty (service contract)? The new Added or Max care plans cover heated seats - I asked when I got added care on my 07 JGC 2 months ago. I had that plan on my 01 JGC and had the driver heater element replaced 3 times (2 under the ext warr, 1 prior under the 3/36) but now 3-4 years later no more failures thank goodness. I think the problem with that old style is it's easy to leave the switch on all the time, vs the new ones (and our Chrysler 300) have momentary switches that reset when you shut the car off (but they don't come one when your remote start the car to warm it up before your leave work like I did yesterday at 2 deg ... ah, I guess that would be just too cushy to have both hot air & a hot seat to plop into). I hope you get it resolved since rumour has it the brakes, window regulators and seat heaters are problem areas on these 99-02 models and there was a recall on 02 seat heaters due to fires as well - take a search through these forums to learn more and good luck.
