91 loyal . ea82 sing port. auto 3at convert to 5spd 4wd dual range. 

 

converted this car to a stick. was fun, car drives great. tell shes warm. at first blew code for bypass air control at throttle body. changed it. no code now but after full temp the silinoid on it sticks wide open alowing air threw. same as old one that blew code. new one does not but still same problem.

On the older black ECU's auto/manual was dictated by status of the harness. Sensors, switches, and a ground. If your unit works the same or similar and your driving around as an auto with a stick Im sure there is to be consequences. One could easily be an IAC code and idle issues.

Ide like to give specifics but I fear leading you in the wrong direction as all I am familure with is the older black ECU's.
