So I have an 89 5.0 GT aod. My car is intermittantly running very rough, shaky idle, low power.... My Chiltons manual gives a test for the Mass air to use a voltmerer to check voltage between terminal a and b to be a minimum of 10.5V and mine is reading 14.08V, and between terminal c and d to read .60V at idle and mine is coming up at .78V. Does this sound like the problem?
I have already removed and cleaned the mass air wire with mass air cleaner around 4 months ago, but after cleaning I had taken the motor apart to put new head gaskets on it, maby been like 1500 miles since it was cleaned and upon initial startup I set the firing order clockwise instead of counter-clockwise and it spit a flame out the intake pipe, maby that is what messed it up, maby its not a factor.....
Anyways any input would be appriciated, thanks

first bring the motor back to TDC and redo your firing order

It's NOT illegal. It's just frowned upon, like masturbating on an airplane.

Just recently reset the firing order, the motor the car came with uses the non-ho firing order and I swiched the injectors to match.....
