Question about 1999 Jeep Grand Cherokee
Its sounds like a little koncking when idle but then get louder when engaging the gas.
Hello, this could be a very big problem. I would first off and check that your oil level is fine. Next, the bearings on your rods or rod bearings may have been "thrown" causing this internal knock and this can be a cataclysmic problem which will lead to engine problems. This knock can also be your valves tapping and this can be from a stuck lifter, to bad valve lash, or a warped camshaft. An engine can also knock from a cooling system problem. Your engine can knock from improper timing which causes pre detonation of a spark. The list can continue from a bad oil pump not supplying oil to your system, to a cooling system failure, to no oil, to bad fouled spark plugs, to a thrown rod bearing, to a bad valve or stuck lifter. So, what does this all mean you may ask. If you do not have a friend who is mechanically savy I would absolutely have this looked at by a professional mechanic. I would first however to check your oil and coolant level before this. By the sound of the noise increasing with an increased load you may have a big problem. I hate being the bearer of bad news but at least you caught the problem now before it came a bigger problem. I hope this fixes your problem and I hope you get the problem fixed!
