I have a 2008 C15...
I have a 2008 C15 Cat SDP motor. My issue is when pulling a hill engine will miss. If engine is cool or it's morning time truck will seldom miss. I have put all 6 injectors in it, changed all 6 IVA's both wiring harnesses. All fuel lines, and fuel pump. Also I swapped ECM around with another truck and it wasn't the ECM either. Where do I go from here?
