Hey gang, found 2 more issues while chasing down my long standing performance issues with this beast, want to lay them out here and see if they make sense to anyone else..
1st off, could not get TPS adjusted properly, would set fine with throttle at idle, , test fine at WOT, then be out of spec when throttle returned to idle. Looking around, and found a retainer cup missing that allowed the throttle cable to move around and never be secured in the same position at the side of the motor. New cup on the way, does it make sense that if the cable were not properly secured, that it may not allow the throttle to completely return to the "set" idle position?
2nd, found the vacuum line on top of the Fuel Pressure Regulator looking like it has not been hooked up in a long time.. the entire surface of the tube has a similar level of corrosion/weathering. does it make sense that if this line were disconnected, the system may be overpressuring itself, causing too much fuel to be injected to the cylinders as the injectors pulse?
Feel free to shoot holes in either or both theories....
