Here's the problem. Car starts and idles like a washing machine. Won't run much. On high rmp (3-2K) I hear a loud tick tick tick noise. Someone said it sounds like a dropped valve?

It's runing on number 1 and 2 (from firewall). If I disconnect plug wires 3 and 4 it'll still run the same. No change. (I get spark to all cylinders)

I checked the timing it's fine.
I checked the wires, dist cap, hall sensor ect all fine
I checked the coil, good ohms.
I checked the plugs, all fine (3 and 4 have a dark carbon coating)

After meddling around with the AMM and the hall sensor, no change. Both are in working order. I do plan on doing a compression test tomorrow. Wiring looks fine.

Fuel injectors are have the same resistance.

Anything else to check if the compression test is good?
