Stopped at a light the other day on the way to work and the engine sputtered and died. Wouldn't restart even with the MAF unplugged (causes a limp-home mode).
Towed to a shop (I'm on a deadline at work so couldn't futz with it myself) where they finally got it to start. It sounded like the ignition would cut out intermittently at idle when hot. Wound up throwing a new crank angle sensor in it and so far, seems to be running well. As a test, when it died initially, I had put a bit of sheet metal under the EGR valve to block it off since I was thinking that it hadn't been closing properly and giving me other issues. Block-off is still in place and check engine light is on though displaying only EGR related issues. Without EGR, the knock sensor will just cut back the timing so no destructive pinging that I have to worry about for the moment.
Figure if all is well, in a few days will pull out the EGR valve to inspect and replace if necessary.
