I have code 332 showing up and listed is what I have done. First off I changed the egr solenoid, have vacuum to the solenoid while the truck is running. I also have vacuum present at the coffee can and present at the egr valve small green line when the truck is warm and at half throttle. I also placed another line in the egr port itself and could hear the diaphragm flexing as I physically sucked and blowed into the line. The coffee can appears to be okay with no holes but I'm lost at this point with just replacing all the vacuum lines. Ohh I also checked the voltage going to the solenoid and have 12 volts present. The truck does not run rough at idle or anytime at that matter and gets about 16 mpg. It's 2wd short bed and has 160,000 miles. If someone could please point me in another direction I would greatly appreciate not getting any more grey hair. Haha thanks guys.

i have a 95 5.8L and i have the same issue, i smoke tested it and no smoke came out, along with taking the lines off and seeing if they were cracked, the can has no holes or cracks but my light comes on only when moving though, i can be idled for an hour with no light, but i move 2 feet and its on, doesnt affect performance, and for me, The truck runs and drive, a vacuum leak isn't going to hurt anything, so why bother with it anymore

You are right but if it would help me get another .5 mpg than its worth it.
