Long time no post!

It's been probably two years since I last posted.  Been too busy with  the 
daughters.  Daughter #1 is 4 and #2 is 2 now.  So I've been taking  pity on my 
poor fleet of rocs that has been languishing in the yard.  I  charged up the 
battery on my 86.5 16V and moved it around to where I can work on  it.  I'm sure 
I've forgotten too much about rocs over the past few years so  I'd like to 
run a problem by y'all for some advice.  Here's what she's  doing:
 
Starts up just fine and runs fine while it warms up.  Once it starts  getting 
warm, there is an increase in "soot" in the exhaust and there's that  
"sweet/rich" smell to the exhaust.  When I rev it I get a lot of black  exhaust.  On 
the road it runs like a scalded ape, just with the black smoky  exhaust.  
 
I'm leaning towards either the O2 sensor or a faulty DPR.  Am I on the  right 
track?
