Message	OK long story short. injector died last year did a plenum pull put in 6 new injectors with new rail kit. new style injectors. put it all back together and ran but could tell a slight miss. on wait til this year to pull the plenum again and redo my valva cover gaskets while i am down there and check the injectors. seem ok. put back together and notice sparking from injector coil. put new injector coil in today runs ok but still missing a bit. go down to the PTU and notice that they crammed all the wires way down and melted the insulation and of course causing shorts. cut out bad wires and crimped wires together. getting error 21 which most people are telling me bad PTU. it cranks and runs just tell it is missing a little. if i pull injector coil clips can never really tell which cylinder is not firing. is it best to just replace the PTU?
