When was the last time the vehicle was tunes up and the throttle body cleaned? This is most likely a very easy and I'm expensive fix .
Customer: replied 9 months ago.
I did a tune up around 95k. Also, don't know if this info came through or not but it is displaying error codes P2004(Intake manifold runner stuck open bank 1a), P2177(System too lean off idle bank 1) and P2187(System too lean at idle bank 1)
