My jeep sounds like a lawn mower!! Help!

for awhile now my 96 grand cherokee laredo straight 6 has been sounding like a lawn mower! when i start it, it sounds horrible. i do not know anything about cars so i dont know where to begin or who to take it to. ive always has problems with my car and it never seems to get fixed when i take it in. it also does this thing like if it is going to die out on me, even when im driving i see that my rpms jumped up and my car kind of jolts when it does it. it hasnt turned off on me yet but its just annoying and recently my check engine light came on but i havent went to see whats wrong. would anyone know where i can begin with this loud noise or ever heard of any jeeps doing that jolting thing? thanks in advance!

As for the "sounding like a lawnmower", your fan clutch is probably seized, causing the mechanical fan to turn constantly (it is supposed to free-wheel most of the time). As for the CEL, go to any local auto parts store and they will probably loan you a code reader to find out what the ECU says is wrong. Lastly, clean your battery terminals. Jeeps are very sensitive to bad connection at the battery terminals, even while running.

If you don't know anything about cars, I'd suggest finding someone who does. A friend who is a wrench? High school auto tech program? Or you know, do what most people do: take it to a mechanic. Thankfully Jeeps are simple and easy to work on and really ANY professional should be able to diagnose this without any specialized training.

Go to a autozone or place like that they will run a scanner for free, then you can come back and tell us what it said we should at least be able to give you direction. As far as the noise could be clutch on the fan seized have you noticed a loss in power or mileage? Or it could be just a muffler issue.
