Have rough idle in drive, have replaced maf sensor, iac valve, both o2 sensors, and fuel filter also no vacuum leaks( performed test of removing connection on maf sensor and starting car and idle was fine). Check engine light reflected p0171 lean bank 1 hence the o2 sensor replacement. New plugs and air filter. Not sure what else.
have the same problem?
