black smoke when decelerating
hei guys
i need help! my car tends to spit black smoke when i decelerate. I'll be on WOT then when i let go the gas pedal, black smokes comes out. Its fine when i accelerate.
the car is catless and running straight pipe all the way.
the power feels good still.
could the TPS be the prob?
thanks guys

haha i know u guys gonna say its normal but let me explain further.
the black smoke is not just a puff after letting off the throttle. its a good few secs of trailing smokes when im off the throttle.i feel like the throttle position is not properly close when im off the throttle. so its still feeding fuel when i decelerate. i have a video recording of it on a track. will upload to YouTube soon.
my A/F is roughly 11.8 then lower towards the end
