PO171 code
Symptoms are intermittent, occasionally idles rough at a stop light then stumbles while accelerating , once at speed she runs fine...
Had Auto Zone check and clear the code (PO171)
I'm leaning towards replacing the mass air flow sensor or possibly the EGR valve after checking for vacuum leaks.
What ever happened to just jumping in and getting your hands dirty....I've been researching this for the last few hrs. and still trying to get a handle on it.
Thanks for any insight or suggestions,
Bill,
