I just did the mass air conversion on my 88 5.0 coupe.

the runs well, but it does get moderate rough idle.
any suggestions on what to check?
How much can i tighten the ECU connector to the Comp??

how can i check if the Mass air sensor is bad?

also when i bought the car it came with a small battery. the volt gauge stays a little above the Low red marks. can that be a problem??

thanks

Did you unplug the vacuum line from the BAP sensor?
