My wife's car had these codes last night. My code scanner said they came on at 50mph. I just recently cleaned the throttle body. I cleared the codes and took it for a spin for 20 minutes varying speeds to 65mph. Codes have not come back, nor are any codes pending.
If they come back, are there some simple steps I should take before bringing it in to the dealer, such as cleaning the hoses to the EGR valve? Looking for suggestions.
