If its the LT-1 or if it has optispark I think they call it? check the
little vacuum that goes from the distributor to up top. Mine fell
off & it did exactly the same thing. That was on a 94 Roadmaster
with the LT-1.
As for towing I just play it safe & flat bed it. Thats pretty much
every tow truck around here anyhows.
