Any other things before i replace pcm
my pcm reads 135 after running for 45 min.
i have a rough idle, because i run rich.
ive replaced me ect sensor and thermostat and nothing changed.
i get 4.7 volt at the sensor and used a perclip to hotwire it to make it think it was hot alson no effect.
i cleaned all grounds and my dash reads a little below the middle (180 im guessing)
anything i should do before i dump a bunch of money on a pcm that might not fix it.
