Hi, I need help figuring out why on my 2000 s-10 with 4.3 and 4wd 86000 mi manual trans, the timming is -8 degrees so therefore its very sluggish lack of power etc, Ive changed cam sensor, crank sensor, ecm, coil, spark control even distributor, nothing changed the performance is worse when the a/c is on, I guess due to the additional demand for power, I would really appreciate any help. Thx Tim also I want to add there is no check engine light and with the ecm the knock sensor was changed also. Thx again
have the same problem?
