For posterity and in case anyone runs into similar problems, it appears that the MAF *may* have been dying very slowly. After having the car stall a couple times and almost stall quite frequently this summer, i decided to try cleaning it again. I was a little too vigorous with cleaning it this time and after putting it back in I got ABS/PSM lights, followed later by P0104. I got a new Bosch MAF on Amazon, popped it in, and the car appears to be doing better. I don't want to jinx it, but in the past week i haven't had any more stalls or near-stalls. When the car is cold and i put it in gear, it will dip down to 600-650, but it doesn't sound/feel like it's about to die on me. We'll see in another week or two if that really was a problem, but it's looking promising so far.

That helped for a while, but it seems like it's starting back up over the past week or so. I had the y-pipe off again 2 weeks ago or so and it was still spotless clean, so i doubt it got all nasty already.

I tried this yesterday using a dayco 5060900 belt, i couldn't get the new belt on. I tried slipping it on on both the tensioner pulley and the deflection one by the alternator with no luck. I ended up putting the old belt back on, which went on fairly easily because it's stretched and needs to be replaced. Any suggestions on how to put it on more easily?

My 2002 turbo tiptronic occasionally almost stalls when coming to a stop while it's warming up. It dips down to 500rpm or so, maybe even less, but it then bounces back up and keeps running. It stalled on me completely a couple times, but that stopped once i replaced the air filter. I've tried cleaning the MAF, and I *think* that it helps, but i can't convince myself that the MAF is the problem because it's rather intermittent. I tried capturing some durametric logs, here's the relevant part: RPM THR KPH MAF V AFR 801 4.3 16 1.5 0.92 0.89 778 4.3 15 1.46 0.93 0.9 732 4.3 14 1.5 0.94 0.92 711 5.7 13 1.64 0.95 0.93 695 5.8 12 1.59 0.96 0.94 658 5.9 11 1.62 0.97 0.95 627 7.3 10 1.73 0.98 0.97 606 10.1 9 1.96 0.99 0.99 602 11.3 8 1.99 1 1.02 604 12.4 7 1.99 1.06 1.07 532 12.1 6 1.88 1.15 1.13 578 17.6 5 1.97 1.24 1.18 558 16.1 4 1.88 1.29 1.22 659 11.6 3 1.75 1.31 1.24 778 5.2 3 1.44 1.25 1.19 855 5.2 2 1.55 1.17 1.15 The weird thing is that the throttle actual value goes up as the car slows down, but i don't know if that's in response to the MAF reading, or if the MAF reading changes because of the throttle. Either way, other symptoms would kinda go along with a bad MAF, such as occasional rough idle, when i let off the accelerator and than step back on it it sort of burps(?) Anyway, does anyone know if this sounds like a dying MAF or not? I don't have any CEL's, but I know it's possible for the MAF to be on the way out without hitting those. I'd try driving without the MAF plugged in, but the symptoms aren't constant, so it'd be hard to prove anything. Thanks!
