Working on a GLP080LGNGBE088, serial # B813D04271W-GM 4.3 L V-6, LP
Engine runs fine most of the time ( when I'm on site engine runs good). Customer states that sometimes engine runs really bad- won't idle, hard to start, backfiring, etc. I did a basic tune up (plugs, wires, cap & rotor) with no difference. Propane system has been serviced (Impco system, 125 mixer, cobra vaporizer, VFF30 shut off). Before I begin a deep dive into this I'm reaching out to see if anyone else has had this issue & what was the remedy. Also, this unit has some sort of remote ignition module- does anyone know what it is & how it's wired into the ignition circuit?
Thanks for your help
