1988 Ford Mustang Convertible Malfunction - Engine


Question: I have a maf conversion on my car without the vss signals or the fpm2 wires hooked into the computer. When the car goes into closed loop mode after warming it backfires and sputters for about a minute then goes back to normal but it seems to pull back the power compared to when cold. When I try to do a diagnostic test with the engine running with an actron scan tool the first part is a cylinder id which it can never accomplish I tried retarding timing advancing timing even put my foot on the gas but it never completes the cylinder id, it wants me to keep trying I don't know what the problem is please help me.

Technican: Hello, Which engine do you have? Was this problem (or any problem?) present before the conversion?
Owner: There were no problems before the conversion or after the conversion until some time I'm not sure of. I bought the car with the problem but know the previous owner. it's a 302 v8 with a 90 eec4 computer
Technican: Consider shopping around for a known good distributor at local salvage yards. You should be able to find one for $20-40. Unless you can get your hands on the tools to disassemble the distributor and replace with new parts.
