280Z engine backfires randomly and painfully
Reading a lot about Z cars running fine then stalling like out of gas. I have
a 77 280Z engine with SU carbs. Car runs great first 15 mins, then
sputters and backfires out tailpipe. Rev engine and it chokes, sputters,
backfires (sometimes out intake - can see with air filter off) then catches
and runs great, then does same stuff again. Any ideas of whether carbs or
electric is problem?
