My wife's Cherokee is running badly.........well....sometimes. That's the pain of it. It doesn't do it all of the time. It doesn't seem to have anything to do with the temperature of the engine either. I have checked several forums and have come to the conclusion that first, I should check the pressure at the fuel rail. If that checks to be o.k. and it's not the fuel pump I plan to start changing out sensors. Can someone tell me where to start in this process, or, perhaps, give me insight as to how to fix this? It has a 4.0 in-line six cy. Auto trans.
I am not a mechanic, but I'm not afraid to attempt the work, except the CPS. I hear it's a real pain in the .........
Thanks for any and all help. tommy
