1983 Plymouth Scamp GT - Lacking in Performance

SSVDP: In case I can't find this service bulletin, am I correct in assuming that i would go about this the same way I would in, say, a tube amplifier? Separate the O2 sensor wires from the 8-bundle, and seal with heat shrink and maybe a small plastic tubing… And just the fact that they are away from the other wires is enough to do the trick? Do I need to reroute the wires too, like along a certain line? Sorry to be so inept, never seen an 02 sensor before

Dartnabout: If you can track it down (i haven't had any luck) wanna send it to me? i'll do the same

I'm very curious because i've still got the stock carb, and basically any issues i've had in the past few years have included a carb adjustment in some way, or that has been the only issue.

Thanks!
