@vile,Can you refresh my memory of where the EST is on the 87 5.7 setup with the TBI? I don't think they found it. He told me mine doesn't have one. I was there when he was looking for it, so, I know he did try. Anyway, Also, do I just disconnect the battery to clear the codes? I talked to him earlier and told him it was the same... He said to bring it back and he could check compression and the push rod position..
ok, timed it at operating temp, and with the wire unplugged. I disconnect the battery and touched the red to ground. Is that good enough?If so, then I am still having problems... what next?
