Lean / Rich Codes
Posted: Sat Jun 27, 2015 1:41 pm
I'm consistently having the Check Engine Light come on after about 10 minutes of driving the car. When I put the car into to self test mode I get the following codes:
41/91 - Lean during the Continuous Memory Test
and
42/92 - Rich during the Engining Running Test (with the car at operating temperature)
I just don't understand how I'm getting lean codes out of Memory but am getting rich codes during the Run test. I replaced the O2 sensors about a year ago when I initially tried to fix this and this morning I replaced the MAF sensor with what I believe is the correct one (purchased from AutoZone).
Any assistance would be appreciated.
