That the thing its bouncing 14.3-16.1-16.16 some times on scanmaster AF 05, L8 28-34 jumping around, BAT12.9-13.3, INT 128, BL126, ATS 87, IAC went from 47-50 cross count 252 no mal codes. I'm gonna order all new cables from Caspers and couple volt fix things I guess. I'm going crazy trying to chase this down

What was the A/F ratio?

Get that voltage problem fix then look elsewhere. Voltage is tooo low. Without a great alternator nothing will perform properly. I have a Powermaster 140 amp alt. Everything works well.

New alternator is what I would do if EVERTHING else is tight.

The top was a/f bounce between 14-17 some time that's the problem I'm having. I have an 87 GN that I switch known good parts from to no avail
