  1. So that's why I don't have a problem with the engine even if the air filter box cover never ever fit tight, it before the MAF. I can't tell you how many times I read on car groups someone who replaced $2000 worth of stuff to fix a problem with P0420 and never got it fixed. You got to find out why something happened not throw parts at the car.
