Usually indicates burnt oil getting through your exhaust, Some will say blown head though its only happening at acceleration plus you should never get black smoke from a blown head. You should normally be able to tell if its oil due to the smell it causes.

You should normally be able to tell if its oil due to the smell it causes. Black Smoke= Running Rich--too much fuel look at 02 sensor, map sensor Blue Smoke= Burnt oil-- Valve stems White Smoke=Coolant in combustion chamber--Head gasket

Oxy sensor could be rooted... Its only $60 on ebay, so worth a swap.
But an EL XR6 runs stupidly rich from the factory. Near 10:1 at WOT... So a big puff of black smoke on a high rpm 1-2 shift or just a bit of a cloud out the back when pushing hard is normal. |

even after a head gasket change still runs fine dosent use any more fuel then normal just changed the oil to something thicker seems to have stopped it

also check your pcv valve as the spring fails and sucks oil in
