loosing power, fuel problem?
i have a 1993 wrangler yj with the 4.0 inline 6. i got it right around thanksgiving and have been having trouble with it ever since. the guy before me said he had just rebuilt the motor, i have decided this was total BS. it started having major problems with loosing power and was making wierd noises. being at college i didnt have all my tools so i took it to a shop to get an idea of what could be wrong and they said that it was a fuel problem and it needed a new fuel pump and the fuel rail cleaned. so i dropped the fuel tank and changed out the fuel pump, then i changed the fuel filter and cleaned the fuel rail. the problem got a lot better but was not completely right. i would drive it for about 10 to 15 miles and it starts cutting out and will eventually shut off, but i can start it back up and it will do the same thing all over again. so i changed the fuel regulator and cleanded the throttle body. got a little better but still is doing the samething. i am lost on what else it could be, anyone have any ideas?
