Can someone tell me what the code P0193 means. My check engine light came on once but went awway the same day. That was right after I put the Volumizer on. No problems since. About 3000 miles, and I flip the switch a lot. Hard to leave it alone.
I have 17000 on the truck and the only other problem is the stinky oil smell in the cab at idle.

I found this site, looks like it has our codes, but does not say it is dodge specific. If it is corrrect mine was a fuel rail pressure-high code.

Moderators, I do not know how to edit my original subject line, I'll start a new one about finding codes.
