2004 Jeep Grand Cherokee Limited (Engine issue?? Otherwise perfect)

2004 Jeep Grand Cherokee Limited Description

This is a beautiful well maintained Grand Cherokee Limited with all available options including tow package, all power options, 4x4, V8, sunroof, leather, etc...
The truck was running great until a few days ago and within a mile or so went from perfect to the engine making an awful noise that sounds like a combination of not getting enough fuel and something mechanically being broken. I am not a mechanic and this was just a 3rd vehicle to get back and forth from the ski mountain so I've decided to sell it as is.
Like I said, the Jeep was perfect before a few days ago so if someone is able to figure out the bad engine situation then it could be a great truck. It is meticulously clean and the tires are in pretty good shape as you can see from the pictures. Everything else in the truck works perfectly other than the scary engine noise that has come up...It really is beautiful and has never given me trouble before now...I just don't need it so I am not going to spend to repair it.
The truck had a new computer board put in about 6 months ago and ran like a champ until the noise. It's always been maintained well w/ regular oil and filter changes, plugs, etc...no leaks or any other issues like that...Cold AC & hot Heat...It will turn over but clearly doesn't want to at this point.
Whoever buys it will need to have it towed. I have the clear title in hand and will do my best to answer any questions that you have. I have not tried to drive the truck since the noise began. Bid with confidence...100% positive feedback for 17 years on Ebay.
Thanks!
