02 lq4 skipping

Engine idles fine. Drives fine for 1/4 mile. After that intermittent skip. I've put in a new fuel filter, fuel pump, soaked injectors in seafoam, fixed vacc leak on egr plate, cleaned maf sensor, no codes in torque app. Tired of throwing parts at it. Any ideas on diagnosing?

Also I should mention when it starts you can turn engine off and crank it right back up and it's gone

How do the plugs look? Are the plug wires old?

Changing plugs now. Not very many miles on them. The engine is in a jeep. I don't drive it alot but I drive it hard when I do.

Forgive me I'm posting as things occur to me. In the torque app I can't ever get the O2 sensors to read complete. The heaters do but not the actual sensor
