Are the valves opening and closing? cracked springs?

Did this problem start after the wire/plug change or are you trying to fix a previous misfire?

Hi, did you use Silicon Grease ?

Did you crack those plugs ?

Would you measure wire resistance AND report ?

What brand of SPW ?

What SP and Gap ?
