Service engine light came on 2012 Nissan Maxima does have high miles. Engine rpm is above 2000 in park.. Had throttle body clean did help and light went off. Back on same problem. Please help
Could be the MAF (Mass airfow sensor) it may need a good cleaning too; it's easy to access... normally you remove the air filter and it's the fist thing you see in the duct going to the engine, The cleaner comes in a spray can and the directions are normally on the can
