Fellow wizzes, need opinion/help. Just replaced my intank pump and new cp3 injection pump (new, not rebuilt). Motor still idles rough, if you step on the pedal (in park) stays high & rough ( like a miss), have to shut down to get it to idle. Shot the exhaust manifold ports and temps are, From front - 1cyl- 230f, 2- 158f, 3- 150f, 4-260f, 5- 273f, 6- 279f. seems to be a problem at # 2&3 cyl's. Could this be an injector problem? Also seem to have a bad diesel rattle (like older diesels). truck is a 05 cummins quad cab 4x4. Fuel fank inspection was clean! Thanks
