My friend has a y7 with a y8 manifold on it. It has had a vacuum leak for a while now. Last night we fixed it by plugging the small holes in the IM flange that only come on 99-00 y8 IMs.

It fixed the problem, he drove it for a mile or two, and the car started to stumble and want to cut off. He pulled over and called me. When i get there, there was smoke coming from the exhaust and around the turbo/exh manifold area. It doesnt smell like coolant or oil specifically.

I pulled the plugs, they are glossy black(ive never seen any plugs this shiny), heres a picture



im not sure if thats from running extremely rich...which in that case, what would happen if the resistor box wiring some how came loose or the resistor box took a **** on us(has 450 dsms)

could something be clogging the exhaust and causing the smoke?

pcv?

any help is greatly appreciated. btw its a greddy kit on the motor, afc(not the hack, wired normally)

doesnt even look like that plug is firing , its really really rich .

and if its a new kit , smoke from the turbo and mani is normal

Its my understanding that if your resistor box went bad (never heard of it happening) that you will fry components in the ECU.

you need to adjust your afc to run those 450's , did you do that?

yes, afc is adjusted, were using settings from the previous owner of the kit that had it tuned with the EXACT same setup. So that answers the question about being a new kit, and if its tuned to 450s

i had that problem


btw is dat gas or oil////


i say check the wiring again
i had a fractured cable once and caused my inj to stay open
i bet $5 is a cable fractured

it ran fine with the 450s installed for almost a week, it only happened after we took the IM off and filled the cold air idle holes(i think) to seal the leak

yea
my car ran fine for 1 mth
it only takes the moving of the harness around to fracture a cable

which wire are you referring to? one of the ones regarding the resistor box?
