My thingy is primarily a code reader but it can display a dynamic reading of a bunch of engine sensor stuff that I dont understand, so it's probably worth a try.

If it's showing realtime sensor data, you should be good.

I guess it could be kinda like if you have bad or missing plugs/wires. Depending on which cylinders aren't firing and their location in the firing order, it might not run that bad. Also, if the injector is stuck, it could still be leaking slightly allowing that cylinder to fire, but run lean.
its runs pretty good at high rpms but still not like it used to.

you might want to get a stethoscope and check the injectors. i would say use a noid light but that doesnt tell you if the injector is stuck. the only way to do that is listen. if you dont want to buy one, ive got one you can borrow.
left bank o2 sensor, figured it out tonight thanks to sharpe. fuel trim difference was 126-140 (right to left). Also decided that i want to put in a 180* thermostat, so add that to the list on the programming fred and delete the damn o2 sensors so i dont have to change another one!
you sure its o2 and not injectors, pistons/engine/exhaust leak?
yep im sure... code 44 i believe
edit: im dumb, replaced the o2 sensor, no codes now but still runs ****ty
