22re engine trouble
Hoping someone might have an answer to this. My truck sputters and loses power when driving. I guess as I reach around 3k rpm it starts sputtering, then when I let off the gas it will smooth out. I have found that moving the distributor a bit helps, but only for a short time. My timing light just went out and have not had time to replace. I have continued rotating the distribute when this happens and it runs much better but then the same issue comes up again. People have suggested the timing chain. Anyone have any ideas on this?

sounds like it could also be fuel starvation, and what you are experiencing is "lean misfire". do you know what your fuel pressure is? it should be around 29 to 35 psi under hard acceleration. if it is significantly lower, it won't run correctly. i've been there chasing it, and at least now, with a good fuel pressure gauge installed, i can diagnose/eliminate fuel delivery/etc by looking at the reading.
