Why won't my monte run right
I bought a 1971 chevy Monte Carlo it ran
good I drove it home and a couple days later
I was driving to the store.. and it started
sputtering and back firing and I had to use
my jump pack to start it ...because it's
completely draining the battery.. and I put in
a different battery and clean the cables and
replaced the ulternater with a brand new
one and the battery still draining the battery
..i also replaced the spark plugs and wires
..please any information would help
