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

 

Is your car eating oil?

 

burnt oil would be bluish hue

 

thats correct...
the car does not smoke at idle or cruising

 

seems like u popped an IC hose.

in general (not sure on e85):

black smoke: overfuelling
white smoke: burning coolant/water
blue smoke: burning oil

 

Checked all my clamps...eveything is good

 

does the smoke occur when the car is idling, or after warmed up and driving?

bad air filter? fuel injector leak? bad timing and therefore misfiring?

just throwing out ideas..

 

No smoke while idling nor cruising....only when I get on it and let off than after 5 seconds its smoke...and its not misfiring...

 

on side note would stroker motor will have bluish smoke? normal?

 

bump for some help with knowledge

 

could be ur turbo is on its way out.

 

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 ?

 

Check your EGR hoses at the throttle body.

 

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???

 

im changing the front sensor tonight...i will keep you guys posted on what happens
