My 2000 SE / 5 spd./ CAI/ Cattman Y & B pipes / has 180K miles, starts instantly, drives with no hesitation after 3 min. warm-up., 21 mpg/city (used to be 25). A CEL lit up 3 weeks ago then disappeared with no performance changes. MAF sensor was cleaned 6 months ago. Could it be the old computer? Anyone w/ similar experience where light comes on then disappears.

 

What’s the DTC?

 

P0101 ..............Maf was cleaned recently and the CAI has a fine nylon mesh, protects MAF from moisture & dust.. The CAI is next to the battery,(24" from the floor) never gets wet
