hello people got bit of a strange problem on my saff ive not long put the head back on after a valve problem and whilst i was there i put 55lb injectors and a msd chip new cap and rotor ect.....

the problem ive got is that i'm getting a continuous spark to number 1 but 2,3 and 4 only spark the once when keying over

each plug sparks once when the ignition is switched on and off also, is that normal?

cheers, dean
