I had a diagnostic run on my VX to see if the pros can find anything that may have brought my MPG's down (from about 16-17 to 12-13). I did run Sea Foam through the system and it seemed to boost it up a bit, but no more than 14. One of the issues they said that may be at fault is, I am missing the Screen before my MAF Sensor. I have cleaned it a few times and have never seen one, have looked online and see where there are some sensors that do have the screen and some that don't.

Do we have a screen or not??
