I just replace the cylinder head gasket and when i start the engine it's normal, but when i start to drive and the temperature gets to normal is not that often but the engine starts to die like if it was working in 3 cylinders, but when i increase the rpms the engine gets normal... I need some help...

 

I wonder if the igniter is on it way out. Check into getting a rebuilt dizzy.

 

where is the igniter located??? And now i think is the timming 'cause i move the distribuitor and it work better but when i'm parked the temperature goes up and qhen i accelerate the temperature goes down.. I need help...

 

sounds kinda like it is idleing way down and getting an erratic idle. I would make sure your colant was bleed properly and your ignition timming is set right.
