need help diagnosing why car is running rich

[Spln_Hrd]

the car is running rich .98 to 1.04 volts from the o2 sensor. 11 psi of boost i have colder plugs(i think its ngk bpr6es) i know it is the one range colder than stock it is decently cold outside but my timing is still getting pulled to a low of 0 degrees what could cause this?

i am wondering if maybe one of my injectors is sligtly messed up but i have no idea.

please help

also if anyone has anything to help me post datalogs that would be helpful

You've got knock which is pulling timing.

Have you checked the sparkplugs for tell tales of running rich / lean?
If one of your injectors was fouled.. the corresponding plug would look lighter than the rest.

I'd also check for boost leaks, condition of plug wires and bad gas (stupid winter gas additives).

how would a boost leak make me knock?

bad gas?

a boost leak would make u run rich because all the air that is leaking out has already been counted by the maf. its simple the maf counts air on the way in and cant tell that its getting out. when the maf counts the air what does it do? it gives fuel. more fuel then air now makes a rich condition (sometimes extreme).

I hope your making these observations after the car ( o2 sensors ) are plenty warm?
FYI -bpr7es's are colder.

yeah i have sevens in than

car is warm, what would a faulty knock sensor do?

runing rich won't make you knock i know what a boost leak does i just don't see how it could make you knock, i could see it making you run rich as hell but not knock

Yes it does.. I have dataloged it many times. Mostly "felt" in the higher RPMs/Load since this is when the largest % of air read by the MAS is being lost (i.e under boost).

In my case the vacume line to the EGR was knocked off.
