Need HELP!

Looks like the short term fuel trim is almost maxed out in the negative. That would imply the egnine is getting fuel from somewhere other than the regular injector function or that air is heavily restricted.

Maybe a faulty or too large of an injector? They they said they were OEM, Denso not Motorcraft. Or not getting enough air to it. I've done a smoke test as well and can't find any leaks.

cylinder 1,2,3 look normal. 4,5,6 are really fouled.
that definitely means you have a problem with bank 2, the drivers side.

swap the O2 sensors between sides. look at the wiring.
or something is shorting those 3 injectors to ground.
try unplugging the 02 sensors, what happens?

try unplugging those 3 injectors and start the engine. it will run horrible but should not smoke.

last but not least, double check the plug wire order. look at the markings on the coil pack.
