My 95 Monty SR has started missing really bad and it coincided with the seatbelt light staying on.

I have tried isolating each plug and coil but cant confirm if the any plugs, wires, or coils. And at the same time the seatbelt light began to stay on with the belt properly buckled. Sounds like some sort of electrical problem. Any ideas?

Thanks,
Ken
