I have a 91 pontiac firebird with the 3.1.. It will crank easily, but rpms
will slowly drop off and kill. The car sat up for about 2 years. I've changed
plugs, wires, dist. cap, rotor and fuel pump on it. We've checked the timing
and it seems to be 180 off. No mater wich way adjusting distributer will it
change. Any help would be greatly appreciated.
