hi guys quick question,

just picked up a 91 fc with a failed MOP/OMP.

pulled the ecu and it has burn marks. Read on the forums that the burn marks are signs of the MOP failing. Now to fix this issue can i replace the ecu it's a N353 ecu. Or do I have to repalce the MOP as well?

See attached pic.

thanks

Burn marks
