ceskimo Posted December 15, 2012 Share Posted December 15, 2012 The title says it all. pretty much. Mechs checked injectors and entire system on laptop, and cant find anything wrong. However; i have noticed that it runs normally while doing a "rolling re-gen". Real pain in the ##s tryin to keep it outta that rpm range while pullin hard. Any suggestions ?

staxx Posted December 15, 2012 Share Posted December 15, 2012 Sounds like you have a injector down have your tech do a cylinder cut out test with laptop while on test drive under load one at a time and the cylinder not changing/no differance will be the issue. This has been the only way I have been able to pin piont these problem . When it acts up does it feel like the driveline is out of balance ?
