2011 G37 CoupeX. 68,000 miles. Attempted to clean throttle bodies to try to fix error code P0106 Manifold Absolute Pressure/Baro Sensor Range/Performance. Map sensor replaced by dealer when I purchased the car 1000 miles ago. Unable to remove bottom allen bolts on throttle bodies using allen wrench. Tried Pb blaster with no success. Any advice appreciated.

 

There is a technical service bulletin (TSB) for your car that corrects a false P0106.
Details can be viewed here: https://infinitig37.com/TSB/ITB12-026a.pdf

Good luck!

 

Try to remove them after the pb soaked over night and while its cold

 

ahhh...you knew there was a TSB...thanks for making me work a little harder to find it.

 

WTF? Comments like this make me wonder why do I waste my time trying to help others.
Next time you have a problem, I hope someone else will give you a direct link.
