So, I’ve been having some very troubling issues with my G35 recently, here are some of the symptoms I’m experiencing right now:

• The AFR is sitting in the 9’s very consistently at nearly any amount of throttle (occasionally it’ll dip into the 10’s or slight higher but for the most part it’s in the 9’s)
• The car’s struggling to go past 2500 RPM
• Lots of hesitation above 2000 rpm
• Last time I checked I’m getting 2 CEL’s: P0340 AND P0345 (I believe they’re related to the camshaft position sensors, I’ve replaced the sensors from both banks with the sensors from my brother’s 350Z but I’m getting the same CEL’s still)

I’m not sure what to do at this point, does it seem like the car could be in limp mode? Does limp mode cause an extremely rich AFR? If so could that have cause the plugs to foul? Any other suggestions?
