well driving home last night i noticed my truck wAs acting funny like 5 miles away from my house never happened before. First off i was like omg wtf!! started smelling gas like it was getting flooded and the engine wasnt able to fire the cyclinders on time so the engine started shaking the car like big vibarations, so now im like fn great. pull into driveway and im thinking what would cause this look out back at my exhuast and i see white smoke i smelt it and it was veryyyyyy gasy (sp) smelling.

So,, anyone know what i should do to fix this, i was thinking a AFC2 air fuel controller, normally used on imports but works great on all autos

 

white smoke is not good. that does not mean you are running rich that is black i beleive. and i think white smoke means coolant. im not 100 percent sure though someone can correct me.

 

Sounds like a blown head gasket. Pull the dipstick and check the oil, if it is over full and milky thats a sign. Check your coolant level also.

 

Compression test will help determine which side is blown.
