2015 Chevy Suburban trouble codes p0172 & p0175 together
What is your question?
What causes these codes to appear at the same time. I understand it's a rich condition in both banks. Have checked air filter and changed MAF sensor because readings on scan tool were jumping around quite a bit at idle, still did not help. Seem s to lack power under acceleration some and when you turn it off wants to "run on" like it's burning off excess fuel.
Any suggestions rather than throwing parts at it???
What makes this problem better or worse?
Same most the time
