Mine has come back on, so it needs tending to. The first time they just cleared the codes, and now it's back. I suspect minor vacuum leaks.

Anyhow ....... when I called to make the appt (which is only 3 weeks away), I said the light was on so did that matter? Only if it's flashing, sez the dealership, in which case do not drive. Who knew what a wondrous device this was?

I heard that from my dealer too!!

Me too!

The light came on while driving down the highway. Turned out the gas cap wasn't screwed on properly. They said that the gas cap issue is the major cause of OBD-II lights coming on.

...to know which MILs are important and which aren't. AESIS and your manual both state that flashing MIL indicates conditions which can damage the catalysts - thus EPA requires immediate repair. You can still melt your pistons with a non-flashing lean code but it won't harm the environment, so no one cares (but you).

My '00 threw both banks lean DTCs with a solid MIL. Since I knew the codes were *BAD* I marched in and got a same-day replacement of my MAF sensor. Would a 3+ week wait while running lean have melted anything? Dunno, don't care.

Know the codes!
