Question 90 GP Error Code 43

I have a 90 GP LE 3.1 (T) coupe that has consistently had the check engine light on. I keep getting a 43 code. I have replaced all coils, the ECM, and the crankshaft position sensor. The car runs much better, but still feels a little under powered. The only things I can think of now are the MAP and/or camshaft sensor. I would rather just fix the problem rather than just throwing parts in the general direction. Any ideas?

the ignintion module would be next on my list to check. Also check the wiring harnesses to it (there are 3) to see if any are corroded. The module is mounted to the front of the engine block, and is subjected to a lot of road grime and such.

Thanks, I'll check out the wiring. I actually changed the ignition module when I replaced the coils. This car suffered from several years of leaking power steering and the bottom is covered in crud. I'll check out the wiring, it may just need to be cleaned up and rewrapped in places.
