Unhappy Help

Hey guys, I need some help/advice on what might be happening with my diesel. When I rev it in neutrel not under a load it feels like it is missing or not hitting smoothly around 1800 to 2200 and at around 2300 or so it seems to fall off when i'm in gear. I don't feel the miss when i'm in gear. Also when I lug it it seems to not hit right like a ricity - rack or john deere sounding kinda. I don't know how to explain that. Could this be a start of a clogged fuel filter? Injector Problem? HELP !!! By the way it is a '95 12 valve 5 speed :thanks:


Thanks for your help in advance,

Luther

In neutral, most 12v just don't rev well without some adjustments. Not sure though with it missing and problems in gear. Might be fuel filter, might be lift pump if you know your not getting fuel to the injectors. Just my thoughts.

Sounds like slipped timing or a fuel deficiency. Can you get a fuel pressure gauge? I'd start with a new filter. Then overflow, then LP, then check timing. A gauge would really help.

When you are in gear it will start to fall off at 2300 rpm because its hitting the governor and it will not fuel as hard.

Unless you have pissed with the governor I doubt it. With my experience I had a 2900 rpm sputter and a lift pump and overflow spring fixed it but could be timeing as well.
