I did a head job on my 89 v6 4x4 yota. It ran crappy afterwards traced all wires and vacuum lines. The truck would lope at idle have a miss, the computer would put its self in limp mode and it would run hot sometimes and other times not. I took it to 2 shops both basicly said i neede a new engine harness wiring, so I got a good one from a salvage yard. I installed it this morning and now truck will not start at all. I believe the distributor wires could be crossed but the pigtail on the distributor is cut. I do not know which are which ie. NE G1 G2 G-? any help!
