Hey guys, had my 2006 G35 coupe for almost 3 years and this is my first post. So if you want to dog me about searching, I've been there and done that.

Here's the problem guys...

2006 G35 coupe 5AT, K&N SRI, eBay shorty headers, Megan Test Pipes, and HKS True dual Replica.

I've been getting check engine for bank 1 sensor 1, I'm guessing that's because I have test pipes. And after getting a very minor headers leak repaired this morning, he unplugged my o2 sensor passenger side to slip it over something and plugged it right back in. My SLIP and VDC OFF lights are on now . I tried resetting and clearing the code, it comes back after 5 minutes of driving. I also have 4 new codes that my scanner read; P2A03, P1148, P0130, P0133. The car drives the same but seems to be a small power loss and it's really bothering me that these lights came up. Any suggestions of should I be looking into ?


BTW I have a $1000 race in a few days against VW Golf GTI with intake and exhaust and need this fixed so I have no excuses when I lose 😜😝 (Sike)

 

Check the cam sensor plugs, they might have been pulled out if the clips are broken.

 

Thanks for the reply bro, are the they behind my engine? And today I notice my power loss pretty bad and my exhaust is much quieter

 

Didn't work, how can I tell if my upstream AFR is bad when I have Megan test pipes? And will bad AFR cause my slip and VDC Lights on?
