CEL: too rich-wtf?

[yellerandahalf]

Alright, now I've got a CEL for too rich on sensor 1. I was pretty sure this was the case, but I wasn't sure. I'm wondering if the 255 lph fuel pump could be causing it?? I have the stock pump at home, but I don't see how this would really make a difference.

Do you got a A/F guage?

 

[TheMAN]

yes the fuel pump would cause it because of the high pressures... and so would an exhaust leak

 

[yellerandahalf]

no A/F gauge yet. My dad's letting me borrow his AEM out of his FD for a few days; I'll see if that shows me anything. You're kidding about the exhuast leak, right? Unless it was before the O2, i don't see how in the world that would make sense. even if it WAS b4 the O2 sensor, i can't see it making that much of a difference.

Also, would higher than normal fuel pressures throw a CEL?

Tried replacing the fuel pump with the stock unit. Same results. I'll try the regulator next. Any other ideas?

[yellerandahalf]

Yep, Exhaust leak for me. Smell like gas at the tail pipe

im throwing the same code. Does your car feel like it lost some hp?

 

[yellerandahalf]

dude it's bogging so bad it hardly accelerates. I'd say I lost some hp.

[JOMO]

oh, mines not to that extreme. Just about a 10-15whp loss.

 

[yellerandahalf]

mine's a bit insane. I've purchased CWill's old MAF, perhaps the one I have is just dead.
I completely took the turbo system out of the loop today, made a short intake pipe, and ran the car NA. Took me 20 minutes, and it shows you how riduculous 200 dollar intakes are. However, the car still runs insanely badly, but I have ruled out the possibility of a pressure leak in the turbo system causing the issue. It could still be a leak in the manifold, but I sincerely doubt it.
