Ok the car all of a sudden started running real rough idle fluctuates between 840-740rpm.......but the motor you can see is idle ruff like shaking more then it should.....white smoke is puffing out the back smells alot like gas though.

I am running 5lbs of boost with 12degree timing off the ignition. I havent upped the boost since I blew the headgasket last time...the head gasket is new and Im not sure wtf is wrong. I put new plugs and gapped them at .035 yesterday.....thinking maybe bad wires but that doesnt explain white smoke....could a bad injector be the problem or could it be another headgasket I doubt thats even possible though I've been real delicate with the car so I could get new fuel pump and tuning.
