Quick question about the weather temperature
So since the weather has dropped in temperature I have been getting a cel for system too lean and maf signal is high. But during the spring and summer I never throw a cel. So my question is should I have had two maps, one for warmer climate and another for cold?
Thanks |

maf specific codes should never be ignored. it can be a recipe for disaster. i suggest you find someone with a working maf and try it. you can try cleaning yours but it sounds like the maf itself is on the way out, proceed with caution and do not WOT it. failing maf's often lean out the fueling.

maybe you have a vac leak, boost leak test the system first and see if the problem subsides. if one of your codes is an IAT code or volt, it's more than likely because the maf is bad.

if you clean maf sensor always best to let the car re-learn idle.
that means as long as it takes for the coolant fan to switch on. |
