Pegged very Rich.. can't idle. Help?
Hi Folks,
All of a sudden my car goes full rich across the board... can't idle... WB02 showing 10:1 at idle and while driving, cruising and in boost.
What sensor could go wrong? NB02? vaccum leak? AFM?
My set up is on the signiture... Thanks for any respones or comments.
Regards,

No luck...
Removed FMU... idle crap
Replace OEM FPR... idle crap (Checked Fuel pressure = 45 psi)
Replace Walbro 190PH with OEM FP... idle crap
Funny thing was... when I unplug the YELLOW connector (prime mode) the car idle solid = 0 psi pressure in fuel rail.
Next... replace injectors...
Anything else?
