ok so as in my other post, dang these old efi electronics, i stated that my truck is running badly and that it has an eratic rough idle and doesnt run as good as it should, when i tested it, it showed "profile ignition sensor circuit malfunction"
but i think it may also be the manifold absolute pressure sensor, i know on these old efi trucks that you can change alot of things and still not fix the problem, but i love this truck cause it was my grandpas and i really dont want to change it to a carb motor, so any help would be appreciated
