2004 dodge hemi truck
Sounds like you may have an issue with the EVAP system. If CEL is on, have it scanned. You will probably find an EVAP code. https://www.youtube.com/watch?v=Ox2B0pwGNIU
i have replace the egr and the caner
Okay, so I take it the check engine light is out then? I found this comment in a Dodge forum. Maybe this is the cause of your issue. Here's what the guy said: My truck did the same. It happens at slow speeds called by the feds as "parking lot speed". There is a dodge memo on it but no gov recall because of slow speed. It's a software up grade. The shop can down load it into the computer of your truck. There is no charge. Dodge and the d.o.t. made a deal not to recall because there were no accidents. So that's what this guy claims. I guess you can call the Dodge dealership and ask them about this upgrade in the software. If you already replaced the EVAP canister and the EGR valve, this may be your ticket.
