PO171 Code. DONE IT ALL
Hey guys....
I am in a pickle. I had the PO171 and the PO420. I cleaned the MAF Sensor replaced all vacuum lines that were broken. Ran a air leak test it all passed. Ran the MAF test, pass, 02 sensor, pass. I ran Cataclean, PO420 code is now gone. PO171 is still here. Now the shop is replacing the fuel filter..... Please if anyone knows. What are the specs for the wave length of the front Sensor compared to the rear?
Thank You
