OK guys, I've had this problem for a while now. Anytime I drive my truck for a long distance. Here is what I know:
1) stalls after an hour or so of driving, drives fine before that
2) Didn't happen once all winter and is now starting again
3) Started around the time that I deleted my EGR
4) my fuel pressure drops to less than 20 if it tries to stall at highway speeds. 5) Drops even lower (to about 5 or 6) if I'm idling or accelerating from a stop
So I'm assuming this is a vacuum issue, correct? A leak maybe? What's the best way to check for a leak? I tried spraying all of the vacuum lines with brake cleaner before but nothing happened. I also tried to spray down to the vacuum line behind the intake, but I'm not even sure I reached it.
Is there anything else that this could be?
