black smoke after WOT
ok, so i have the weirdest problem.....
when i go WOT and let off after 5 seconds, i leave a big trail of black smoke....
i had my check engine light on, popped the codes, and it threw the egr valve code twice.... than i think my front 02 sensor is dead....than it threw a code of running too rich...
im running e85.....
i checked the vaccum hoses for the EGR and their all hooked up ...
the car does not misfire..
can it be that my egr valve is going out???
can it be the front 02 sensor??
plz i need some help on this

Sounds like you are dumping fuel (running rich on throttle lift off )....the fact that you think your o2 sensor is bad and the code says you are running rich - well there is a start...
Log your runs and see what your AFRs jump to after WOT runs....
Also, when cruising, what is your AFR ?

my AF stay between 14.7-15.2 cruising...sometimes goes lower in the 12s....
my egr hoses are all hooked up..they are zip tied down...
the AF do go down to 10 flat when i let off though when i go WOT....
can the sensor really be the culprit???
