Update: sorry but when I said "U-shaped vacuum hose on EGR" I meant the u-shaped vaccuum hose on the "cannister Purge valve". Also, yesterday on way home made it 25 miles before engine died, then happened two more times before getting all the way home. On way in to work today tried running w/o A/C on, temp gauge only got a little bit over half-way mark, problem happened after 20 miles; raised hood and pretended to do something for ~ 5minutes, then started right up and made it remaining 10 miles to work.
I've been reading more on this forum and becoming an auto-hypochondriac. It's quite possible that all the hub assemblies on this car are original (I'm at 120K miles now). It seems like there is more "road noise" than I remember, coming from the front wheels. Not very loud, but more than usual. While waiting the 5 minutes, I felt the wheels and the two front were noticably hotter than the two rear hubs; the front driver's side noticably hotter than the passenger side. Noise doesn't change when turning left/right. I'm OK with replacing the two front hubs, since they've done their duty and they may pose they're own problem soon, but could a failing hub/sensor cause this engine-dying problem?
I haven't received the parts yet (mail-ordered), but will be able to install new plugs, wires, fuel filter and front O2 sensor this weekend.
Thanks///
