2003 S 115k miles. No recent work done. Normal sooting on the tailpipe, no oil burning. I'm actually about 2k miles past when I should have changed the oil and the dip stick is still within normal range. I'm changing the oil today.

I need to get more familiar with the Durametric, just got it a few days ago. I was reading about this.

They said I would be wasting money and told me to get a new MAF sensor. Ordered it from Rock Auto since it was cheaper. Never got the code since.

Oh, yes this was another fix I read about. I'll clean it today. I forgot about that one.
