Hi all,
New to this forum, so I apologize in advance for the length of this post... I am just running out of ideas and places to try to get some answers...
I have a two part problem, it involves an 89 F250 Pickup primarily, but I will be using an 82 Bronco to solve it (I hope)
Part 1
The main problem is, the pickup simply no longer runs properly... its an 89 with an EFI 351w, and an E40D transmission The truck was my grandfathers and sat a very long time, it only has 50k original miles on it.
It started by acting up intermittently.... running badly, when the check engine light came on, then running fine again when it went out, then back to running badly, not the light is all the time and its running badly all the time.
This truck is OBD1 so information from scans is minimal. I have repaired all KOE on/off codes except one which says "Idle RPM out of range". It had many with the EGR valve, EGR position solenoid, etc.
The catalytic converter was bad, and has been gutted.
The truck has been to 4 different shops, INCLUDING FORD, and NO ONE can fix it...
It has had the following replaced:
EGR Valve
EGR Position solenoid
O2 sensor
Distributor w/module
Computer (twice)
TPS
All new filters, all new tune up parts (plugs, cap, rotor, wires), fresh gasm fuel injection cleaned, throttle body cleaned, etc.
What is happening, is the truck will idle rough, then just stall completely randomly (you can crank it and it will restart), idle will go up/down, and its consuming a huge amount of fuel... it will backfire out of the exhaust on deceleration. When you take off, it will accelerate, then BAM!!! slam gears when shifting (throw you back in the seat hard)... basically the truck is, in my opinion, (and some others), NOT talking to the computer... It doesnt know how to idle, how to advance timing, when to shift, etc. its like its running without the computer, and just doing whatever the **** it wants... I have sunk over 1k in parts into this through these 4 places and no one can fix it. I am at the point of giving up so my first question is, Has anyone seen this before, and have a suggestion on a fix? (I know its not a bronco, but its the exact same driveline an 89 bronco would have).
Part 2:
If no one can give me a viable fix, I have decided to finally junk my 82 Bronco... it has a blown motor, but everything else is still working fine... it still runs (barely) and drives, shifts, etc. good 4wd, etc.
I want to take the transmission & xfer case, front diff, and put it all in the pickup making it a mechanical shift. then take the fuel injection and intake off, and put a new intake for a carb on it. So my question is, does anyone see any potential problems in doing this swap?
I would be going from an E40D electronic automatic with overdrive, to a plain ol C4? (I think thats whats in the 82 bronco), and going from fuel injected to carb, (which will need a fuel pressure regulator to drop the fuel psi down to what a carb can handle).
Thoughts, feedback, Help????
Thanks so much
