Run a diagnostic test on it to find out the cause of the light coming on so the correct parts can be replaced without costly guesswork.

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

I own a Grand cherokee 1997 V8 5.2 ltr engine. It keeps saying "CHECK ENGINE". Secondly there is so much squeaking noise in the frontal underneath.


i think its time you got a greener vehicle ,check engine light could be anything from a split rubber hose on a vacumn pipe to a oxygen sensor ,also the noise underneath would need a mechanic to jack it up and have a look ,why not buy a nice peugeot partner or ford courier diesel manual for work
