This is a "start-over" from my previous post: http://www.2carpros.com/questions/1996-gmc-57l-vortec-no-power-in-gear-good-idle
The other post just described symptoms, I have stumbled upon something else entirely, that I've never seen or heard before.
The entire passenger bank is completely dead. The exhaust is cool to the touch, not even trying.
I replaced plugs/wires and pulled the wires off one by one from the numbers 2,4,6,8 cylinders while the truck was running, and there was no change at all in the idle.(Yet if I take ANY of the driver side wires off, the truck nearly dies) I took the plugs out one by one and grounded them to the exhaust and saw a healthy spark from each plug and each wire. So I know it's getting fire.
The plugs had a small amount (thin layer) of gas, roughly the size around of a pencil eraser on the very end (Round part under the bend), but they were by no means soaked with unburned gas.
Any ideas where I should start checking?
(If it's worth mentioning, I do not have the breather on and the air suction into the throttle body is VERY loud.)
have the same problem?
