Interesting, thank you. Question. I initially had the p0171 code for secondfary air pump. When i went to check this code i found a broken piece of vacuum line between the air pumps (i think this is what they are called) and replaced. It made that code go away and thats when this p0400 showed up. Do you think it could be the air pumps? Is there a way to test these?
