I'm working on a 1986 Bronco 2 2.9 that was brought back from CA. Finally got it running, but not well. It usually starts right up, but misses intermittently.
I've been chasing my tail on it for a while, so any help is appreciated. Here's what I've tested and/or replaced:
New distributor (incl. TFI module, cap and rotor).
New coil
New plugs and wires
Tested fuel pressure, 32psi while running.
Tested for spark at the coil. Obviously has spark while running, but cuts out when the engine misses (so I know there's a spark issue, not fuel).
Power to coil is good.
Coil signal (green/yellow wire) cuts out when it misses.
Fault codes 67, 18, 22.
I feel like I'm forgetting to mention something, but that's all that comes to mind right now. I'll update if I remember anything else.
Thanks in advance for any help you can give!
