Ok so i pulled the engine and oput it back in, checked every single connector and sensor..nothing looks out of the ordinary. My fuelk filter IS disty. Car hasnt run becaused i broke my SS clutch line so i had to order another one. I floor it and at high rpms i get black smoke. I replaced front oxygen sensor. Any ideas? can a dirty fuel filkter cause it to run rich?? im sorta lost LOL i do feel however that im sorta close to finding the problem since i did almost everything..

-dont know - but i would guess it can make it run rich.

Other things to look at (maybe)-

- Maybe Coolant Temp Sensor is out and the ecu is dumping fuel to get it to the right temparature?

- Is the VAF adjustable - to make the mixture lean?

- Try running a ground wire to the metal part of the o2 sensors that's sticking out - It helped my engine lean out a lot (i am thinking about a 4-wire conversion) - it may not be the same for 6 cyl though.

I have the same problem. At high RPMS black smoke just barrels out from underneath the car :\. My gas mileage is PATHETIC (350km per tank). The smell of fuel coming from muffler is soooooooo strong.

What Im doing is replacing fuel filter, replacing oxygen sensors and thejn replacing coolant sensors. Ill try to replace the vaf but that this is so pricey :S i get no codes for any of those.. i think it may be the iac.. not to sure. let me know if any of u fix that problem. anything over 5k roms PUUUFF black smoke..
