Anyone guess what would cause some plugs to foul and not others?

Car developed a little "pop" every few revolutions...like a miss...no codes..runs good above 2500rpms..below that it misses a little. Checked the plugs and some are burning perfect while others are fouled...auto-tap shows some misfires on some cylinders. Changed plugs...wires..coils...no difference. Plugs foul after a few miles. Valvetrain is good...no broken springs.
leakdown test next i guess.

No oil whatsoever on plugs...just wet from fuel. Thought maybe injectors..they are new 36#s from SLP. Thought for sure it was spark...but leaning towards too much fuel...but the random cylinders shoots that in the ***.
Car never used a drop of oil since the 383. Changed O2s also.
Thanks for the leads dudes.

Swap the wet cyl's injectors with normal and see if the condition crosses over with the inj. I am sure you tuned for them, but you could have faulty inj's or something even new.

Thats my plan..everything has been tuned and running fine for over a year...this was all of a sudden. Im thinking stuck injectors from some **** that got in right after a fillup...hell I dont know.
