headgasket or just airbubbles in the system?

 

you could be running real lean or having dizzy problems

 

wouldnt head gasket cause white smoke?
How do you check your air fuel ratio w/o a gauge

 

I would suspect head gasket. Also might want to check your water pump, impeller blades might have took a dump. Does it stay cool when driving? Whats the fan doing?

 

Yeah if your getting white smoke its your head gasket check your radiator and see if there is a little oil or check oil for coolant
