Car has been running well till now. when i start it , it sounds realy rought and the car shakes and it tends to die if i dont push on the accelerator. after about 1 min of this stumbling its like the motor catches on and i get power an it sounds normal im wondering if i need new spark plugs? thanks in advance.

 

help please

 

That, plug wires, or the optispark.

 

mine had that issuse awhile back but i ended up haveing a loose wire from the msd box to the coil, check all your wires, plugs, and opti spark like the others said

 

turns out its my fuel pump when we checked fuel pressure after about 4 min instead of the 40-47 psi i had 18.
