Hello, I have a 1996 Dodge B2500 Conversion van with 5.9 liter. This engine was replaced with a rebuild in the summer of 2004 after slipping a rod bearing. I done a complete tuneup on it about a month ago (plugs, wires, cap, rotor, & coil). I was hoping this would solve the Code 11 problem. I use the van to tow a camper. This check engine light problem only comes on after the van is warm, under load of the camper, overdrive off, and high RPMs when pulling up a hill. I notice no change in engine power or performance. A search on the Internet indicates that a code 11 either is not normally recorded or will cause the engine to die. The engine has never died. Normally the check engine light goes away after the engine has been off over night. Any ideas? Thank you, Fred
