My trusted mechanic tells me the leaning module in my '77 New Yorker is shot. The car will start and run, but falters and backfires when the accelerator is advanced. From what I've seen here at allpar I need to make some changes...I am not much of a mechanic. Is there a kit or source available with the needed parts and installation manual? I'm In the Colorado Front Range and would be happy to talk to someone hereabouts with some knowledge about this. Thanks.
