Go to Checker, Autozone...or similar. Ask them to reset the check engine light and read the error code. There is no charge and its often something small. Spark plug misfire, fuel filter, PVC valve, or such.

My 1999 jeep grand Cherokee limited edition V8 4.7L is knocking I put oil and my oil gauge is on 0 why is that?

I think you added oil a little to late. The knocking sound is the bearings. The reason you now have no oil pressure is the oil pump has failed. The 1999-2000 limited have what is called a moduler engine. Used engines are hard to come by as there are 2 different ones One has a 32 tooth reluctor on the crank and the other has a 28 tooth reluctor. They are NOT enterchangable. Sadly this motor is known for design flaws and is expensive to repair..

Knocking noise

First confirm the oil level is adequate by checking the dip stick. If the oil level is okay you may have a partial blockage that is starving the oil line leading to the sensor. Missed regularly scheduled oil changes may result in this happening.
If sludge is the problem your dealer can recommend an oil additive that may clear out the problem.
You may also have a failed sensor as well.

My jeep has a knocking sound coming from the engine and makes the same clicking/knocking sound when I'm accelerating what could this problem be?

noisy lifters, or piston slap, i just had one where the piston went through the block, try on your next oil change putting a liter of tranny fluid in it with the oil, the better lubrication will settle a noisy rocker

1993 jeep cherokee 4.0 HP I am having a knocking sound during acceleration under load. Also with the a/c on during throdling up the engine quickley is also knocks. Whats up is this detination, What...

hi i think my last post was lost for some reason., but here it is again, the knocking sound you can hear is probably the big end bearings worn, these are the shells that go between the conrod and the crank shaft , it sounds like they have worn either by lack of oil at some time, or just through age and use, this is also normally accompanied by low oil pressure light coming on but not always, 2 options you have are, another engine, or repair the bearings , but this will depend on how bad the crank has been damaged by the worn bearings..hope this helps please vote and rate thanks

Knocking noise in engine 1998 jeep cherokee

Knocking noise can come from one of three places. Broken flywheel, Worn rod or main bearing. (bearing problems usually are accompanied by lowered oil pressure) An experienced technician can usually tell which is which. If bearing wear is on the rod bearings only and is light, it can usually be corrected. Main bearings require engine removal and is far more expensive. The oil pump should be replaced with either, but is not the cause of the problem. Extreme wear on bearings will also damage crankshaft. If so, it must be replaced.

You definitely need to put a mechanical gauge on there and check for ACTUAL oil pressure. It is possible that the passageway to the sending unit may be plugged with gunk. If oil pressure is not correct or if in doubt, do not drive it 'till you know for sure what's going on in there. No noises tells me that it is likely not serious but an engine is just too expensive to gamble!!!

Have jeep engine light on

Check the Oil in the Motor. If it is Low, Top it off and see if the Knocking Quites down a Little. This could be a Bad Oil Pump.

My 2000 Jeep Cherokee Sport started having a rythmic knocking sound while I was towing about 800 pounds on a trailer over the weekend. I hoped it was low on oil, so I added 3 quarts. However, the sound...

3 Quarts? If you had to add three quarts you probable burned out your Crank bearings. Make sure you did didn't overfill the oil. Change your oil and add some additive to it. If it still knocks, it's probably your bearing. Pull engine, replace crankshaft and rod/main bearings.
