[theboss88]

ok all i did was put new o rings on the injectors, change the plugs and wires
the car just misfires and pops. when you try to drive it it just dies
i got a it block away and then white smoke poured out from under the hood and exhaust and the car died

Did you gap the plugs correctly?

 

[theboss88]

yea i gapped them correctly
a mechanic is saying its the coil pack does this sound right that the car and would have a super rough idle and back fire and pop when i give it gas?
cause i pulled the plugs and they where already black and they been in the runing car for 5 mins

Did you do a boost leak test after the injector o-ring install? I would check for leaks first.

It sounds like a huge boost leak from the injectors, loosen up the rail and make sure the injectors are seating tight. To make sure its the injectors spray some break cleaner at them while the car is running,and if the car revs on its own then you have an injector leak. It does not sound like its your coil.
