Check Engine???

[98GSXboosted]

Sry if this is a repost, i searched but could not find anything similar. My check engine light came on after i installed my greddy BOV which is vented. Is it because it's not recirculated? also will i not beable to pass inspection because of the check engine light?

try recirclulating it and see if the light goes away

I doubt your CEL is on due to the fact that your venting your BOV into the atmosphere. Check to ensure are the cables & connections near the BOV area are plugged in and snug. It could be a non-continuous monitor that's causing the CEL to illuminate so try re-setting your ECU. If all else fails, get/rent/borrow a scanner.

check your front o2 sensor for it's condition as well.

Yeah, my primary o2 went bad. The easiest way you can check if it's your primary o2 is if you have a A/F guage. Mine read lean all the time when my primary o2 was bad (since you generally tap the A/F guage into the primary o2 wiring. A bad primary o2 shouldn't cause those types of problems-just over-richness and poor gas mileage (which is bad enough). Also, ensure the adjustment screw on top of the BOV isn't loose (which only results in a poor idle and engine stuttering after shifts-just FYI). If it's a Type S Bov, RE-CIRCULATE IT!
