vibration at idle
Got a vibration I recently noticed when turning on dp idle program for 1200 rpm. Never really noticed much at normal idle but once you hold rpms above normal idle say 1100 up to 1700 rpm I get a fairly annoying vibration. Remember getting cylinder contribution failure on auto enginuity for cylinder 8 but chocked it up to CPS issues as others noted CPs will give contribution failures especially on cylinder 8. Any ideas on what could be giving this vibration?
