Hey guys my name is Jake, and I am new to this forum. I just bought (3 days ago) an 86 Bronco 2 4x4 manual 5 speed. Truck runs great at idle.
Here are the symptoms I'm dealing with.
• bucking on anything more than 1/8 throttle
• lack of power above 3000 rpms
• bogging at freeway speeds past 1/8 throttle (3rd-5th gear)
• all around PITA
Here are the parts I've replaced
• fuel pump
• plugs, coil, (wires are okay)
• distributor, cap, rotor, tfi module
• O2 sensor
• junkyard ECM out of an 89 ranger 5 speed 2.9
I have been reading these forms for two days and i think I have my timing correct but the tfi module is pointing straight back and before I swapped out the distributor (still had the bucking issue before the swap) the plug in connection for the tfi was pointing towards the passenger side.
Firing order is correct, truck idles great just a bit high. I put the engine on #1 compression Stroke. Pointed the dizzy/rotor at the number one plug on the distributor cap.
I'm at a loss for ideas paid 1000$ for the truck and sold my daily. Soooo this thing needs to run correctly.
It feels like it's Lossing fuel pressure under Full throttle, in first and second gear it will fall on it's face if I floor it but fine if I barely touch the gas pedal.
I could really use some help. I don't have and can't afford a multimeter right now to test ohms and such.
