Hey guys,
I'm nearing my wits end with my car (76 280z with a 78 engine n42head n42block).
The P.O seems to have deleted all of the emissions and most of the vacuum lines (egr, pcv, bcdd all blocked off).
I am having this issue now where i have back firing from the intake at idle (dozen or so per minute) and after warm backfiring out the exhaust and loss of power while on the road. Additionally, the car seems to start at a very high idle.
The fuel system is all custom cell with -AN set up (pressure great), valves adjusted to spec, injectors rebu
