I got trouble codes using jumper wire. I've just replaced a head gasket, engine starts but runs rough and sluggish with no power at all. I also changed the spark plugs and wires. no help there. so I took off EGR valve and it was stuck open. I clean it out and at first seemed to run better but still no power and then rough again. PLEASE HELP, I've been working on this truck for weeks now. What do these codes mean, and how do I fix the problems?
