Po302 po304 po307 po171 codes are showing up, any ideas?


PO 301 thru PO 308 are engine cylinders with possible
misfires & bad coils

PO 171 is a lean condition on Bank# 1 oxygen sensor

If the front or upstream sensor are over 100,000 miles, change
them as preventative maintenance

The cylinder misfires have to be diagnosed & tested any of
several ways,professionally for the most part

Po171 error code


P0171 means the system is lean on cylinder bank number one, with just the one code you could replace the bank one upstream O2 sensor and that will most likely cure the problem.
