Default Intake causing rich conditions?

I'm still throwing the "System too rich bank 1" code. I put my factory downpipe back on, so my only mods are a 3" catback, a TURBO XS RFL BOV and an Injen intake.

It only throws the code when the car is sitting running for an extended time. When driving it's fine.

A couple weeks ago I had a coil pack fry on me and one of my cylinders was not firing. Do you think all this extra gas possibly fouled out the 02 sensor?

Yes it could be the o2 sensor, yes that gas could have fried it, no it wasnt the intake, it was the BOV, because as has been said in this forum 2837812987732.million times, BOV's cause a HUGE rich condition when they vent. Intakes generally lean you out if anything.
No the two do not "cancel each other out"

I was also half asleep when posting that.
It could and probably WAS the bad coilpack.
Although the BOV is certainly not helping things when it goes pig rich every time it vents...

If you're not getting misfire codes though, and recet the ecu since you replaced the coil, I don't think the coil's the problem. I don't think it's the bov unless it's venting when not shifting or laying off the throttle because it gets stuck open. As far as I know, a code saying that you're running too rich means that the fuel trims are out of wack. This could have something to do with the intake, but I wouldn't know. Sounds more like the o2 sensor isn't working normally or your maf sensor is really dirty(possible with oil from the intake). As far as I know though, extra gas can't "fry" an o2 sensor(could be wrong). The o2 sensor might just be old and making the ecu think that you're running rich when you're really not. Might be a good idea to clean your maf, clean the bov to make sure it isn't sticking open, and then(if those things don't help) switch the o2 sensor with someone else to see if that's the problem. If it's none of those, and you have no air leak between the turbo and throttle body, ya might wanna try switching to the stock intake to see what happens?

peace

Oh yeah..
It didnt occur to me that the o2 sensor ISNT bad, I just read it that way. Like I said, Half asleep I had been awake for under 5 min when I posted that, I basically rolledout of bed, got a soda and sat down.
