89 TBI
Recently I swapped my motor for a newer/fresher block.
I can get the motor to start and run with fresh spark plugs and disconnect the dianostic wire. disconecting the bypass wire and setting the timming to 0 TDC the truck runs and drives fine. Once the bypass wire is reconnected the truck starts hard runs rough and fouls out the plugs 90% of the time.
Any ideas? I'm stumped at this time. I'd love to be wheeling this in the fresh powder.
