O2 Sensor?

O2 Sensor

I have a quick question. Since my Speed3 is out of the body shop, with only 2400 miles, the O2 Sensor is on. The body shop replaced it once, but, the check engine light has come back on. My car runs fine. No problems what so ever. I guess since they put the Borla and downpipe on, I will assume the vehicle needs to be tuned?

aftermarket downpipes on 2nd gen speed3's give cel's i believe.

you need to be running an accessport with a catless downpipe of ANY sort because you need to be monitoring your fuel pressures!

If you are running a downpipe on a Genpu chances are that your CDFP fuel pressures will drop below 1600 PSI at WOT which could lead to ZOOM ZOOM BOOM! I would get the Fuel Pump Internals and an AP ASAP.

As far as the check engine light goes, you could get a spacer for the 2nd O2 sensor to fool the ECU to keep the CEL from coming back on. With the COBB AP and the ATR software you will be able to turn off the CEL for that code.

Sensor has not gone off in several months.

Then you should be fine.

Fuel pressure is KEY ! Fuel internals or hpfp should be the fist mod you do , get an AP will save you time / money with any issues .... If you do anything else you make have fuel cut . I'm shocked you don't now .
