Ho hoping to get help. My truck started backfiring. Then I put fresh gas and it got better. Started backfiring again, would get better if I shut it off and started driving agsin. Now it's throwing code 44 and dies when I shift it into reverse. Sometimes it idols fine and sometimes not. The truck is a 1985 with a 95 5.7 v8, has a 86 ot 87 computer, 4 speed granny tranny. It's a fuel injected throttle body. I have cleaned the egr valve, checked for vacuum leaks, changed fuel filters. Any ideas? Motor was brand new 15 years ago and only has 20,000 miles on it now.
