Re: K&N MAF Problem--awful mileage--Please Help!!

If it is giving you that much trouble and the code will not clear you might as well replace the maf sensor or check the wiring real close.
Put a OEM filter back and see what it does.
The main problem on a K&N filter is the oil in them gets into the maf and other sensors.
The newer the truck the more it will affect it.
Was the one you put in well oiled or dry?
Was it just a drop in or a cold air intake setup.
Is the air intake hoses good and tight.
If you have a good scanner I can post some test for that code if it would help you.
