I dont know what really happened to my car but it just wont start!

Last Week i installed my New Exhaust (T1R70RT) everything went fine, Start Up the car all seems perfect! A couple of WOT's Everything was Perfect!

Next 2 Days it just wont start, Black Smoke with Gas Smell Comming from the Exahust!

I took out my spark plugs they were BLACK as HELL! Bought Some New Ones tried to start the car again, It started but with a nasty bogging and Shuted down by itself, So i took the Spark plugs out again, Black Again, Went out bought some NGK Iridium and i installed them The Same thing All Over!

WTF is Happening?

BTW, My Car is a MY03 Boosted @ 12psi and Only 9k Miles on it, Its not a DAILY DRIVER and i Barely use the car Last year i started the Engine like Twice!

Guys Help Me Out Here, Billman Any Suggestions?

Thanks in Advance!

 

Also i changed the Coils with brand new Coils and still the same Drama!

 

since you are boosted, i would assume you have an air/fuel guage?
whats it reading?

 

Nop, I just have a EGR and Boost Guage!

 

from your description, it looks like you running waaaayy too rich.

since you're boosted you might have better help in the FI forum.
