Hey guys, to start off, whatever i'm experiencing is probably nothing. lately when the truck sits idling whether in the drive way, street, anywhere, i've noticed the truck idles rough, smooths out and idles rough again. when it's idling rough, it's not like the trucks going to blow up, just enough for it to be noticed. I noticed it more after I took out my Banks Monster exhaust. The RPM doesn't go down or anything. Any ideas what it might be if it is something? Thanks in advance.
