Only Running On 2cyl "1&4"

Alright So Im on the freeway when all of a sudden bam, car runs like sh!t. So I went home, disconncted the car and started it to make sure it wasnt plugged or any thing, it was fine, So then I checked timing, it was fine, It didnt jump a tooth or anything and lined up with a test light. So I started the car and started disconnecting plug wires to see if all cylinders were firing. 2 & 3 are not. 2 & 3 are bolth run off the same coil so I checked the coil and is's all good. So my question is, what the hell could it be. Plugs and Plug Wires are new.

Thx

Blown head gasket? Do a compression check.

You actually checked to see if the there was spark coming from cyls 2 and 3 on the coil pack while cranking the motor using an ignition tester? What did you do to check the coils? Any CELs?
