I had an issue pop up this while driving, when i press on the accelerator pedal, the engine would cut out/stumble. It didn't do it all the time,seems to be random. What could cause it?? No check engine light on

 

I did a resistance check on the ignition coil, Here are the results:

Primary resistance (Spec is 0.45-0.65 ohms)
Cyl 2&3= 2 ohms
Cyl 1&4= 2 ohms

Secondary resistance (Spec is 11,500-12,500 ohms)

Cyl 1&4= 12,000 ohms
Cyl 2&3= 12,000 ohms
