alright after having problems with ym ign system,replacing the dizzy/pickup coil/ coil.and still having problems i decided to check the plugs/wires.
the first cyl i did was #6 i pull the wire off and the conector seperated from the wire.no big deal,but when i pulled the plug it was white.not lean white,but like out of the box new white,a few of th eother wires broke but all the plugs came out a nice tan color.i fixed all the plug wires reinstalled the plugs swaping the #6&5 plugs.started the car.it still idled smooth.but when i go under boost im back firing into the intake.

my ? is if the fuel injector is dead in #6 would th ecar still idle/run smooth.and would the plug be clean.and could this also be the cause of my backfiring
