Default Control Circuit Cylinder #6?

Okay i finally got my turbo iroc built LQ4 swap finished and I cant figure out what this issue is!

I get a P0356.

I tried...

Changing #6 plug
Swapping coils
Swapping wires
Swapping coil harness'

Also checked the resistance from the pcm pin to the coil pin.

Still have the code....So could this be a PCM issue?


Thanks

Jay

You need to get a copy of the service manual and follow the 18 step test procedure

Figured it out, ran a new wire from the pcm to the coil plug on the main harness and no more codes!

The backfiring was due to more fueling needed under 4000rpm. Pretty much go it smoothed out.
