Jeep keeps stalling along with engine knocks,

try your e.g.r. valve,pcv,and a couple of bottles of fuel additive and a new air breather system.

Hi, My 1997 Jeep Grand Cherokee is doing this exact same thing and no one knew why! I had someone to reset my computer, replace my ignition coil, distributor, as well as a new oil gauge "thingy" (translation:My gauge was showing that I was receiving zero oil pressure, but the component in my engine was broken that allows it to show. So when that was replaced it still showed that I had zero oil pressure). So, someone suggested that I may need a new engine. But, another guy said that I may need an oil pump which made sense.
My truck would slow down while I was driving, cut off, but start right back up. I also have a knock. The fact that it would start back was the confusing part for these mechanics. My check engine light came on as well. They said I still may need a motor, but it's not the reason as to why my truck is cutting off. I'm having the oil pump put in next week. I hope this solves my problem. PLEASE let me know what works for you!!!!!
