I think I'm experiencing this issue. I have a 2011 with 212,430 miles on it. I just had the spark plugs done and two of the coil pack replaced throttle body and Mass air flow sensor. The issue I've been experiencing after these replacement it's not getting gas and won't go over 40 miles per hour. Its dragging to accelerate is it worth fixing the issue at this point already spent so much money with repairs just ready to say the hell with it.
Had this happen, i replaced the oil valve sensor for the under performing bank but you should definitely do both.. the rear one is a little work but the front one is easy!
Im trying to replace both my lower o2 sensor but its literally in the tightest space. Would it be best to just remove the converter to gain easy access?
