I have a 2000 Jeep Cherokee Sport 4.0 129,000 miles and I purchased it back in December for all this snow we got in VA. Anyway it ran and sounded great, it was previously owned by a mechanic and here we are....
Recently I have noticed an intermittent hollow knocking sound until it gets warm which sound like piston slap, I just noticed that two weeks ago. Next, it has gotten warmer and now after driving a sustained amount of time and getting the engine and engine oil hot, I shut the Jeep off and when I turn it back on with the engine still warm there is a crazy hesitation and miss going on. Now The check engine light came on soon after this today and I took it to Autozone and diagnostic said cylinder #3 is misfiring.
What the hell happened to my Jeep all of a sudden. I check fluids more often then I should. I changed the oil when I got it and after 3000 miles on the dot. It was overfilled by about half a quart for 300 miles but I quickly drained it out after I noticed. I used Castrol 10w-30 and Federated Auto oil filters (like NAPA). Any advice please so I can get this figured out.... Thanks
