Ok 2009 hino 268 box truck has surging idiel then stalls hard to start after that will ideal at 900 rpms with pto set
After testing a few things the exhaust chocks engine out I disconnected electric plug now it starts and will ideal at 860
I only have to deal with this one hino so no diag tool have to do it old school
originally came in for loosing coolant found crack in radiator replaced coolant loose was cut in half so checked EGR cooler and found it to be leaking coolant into exhaust system replaced that
and pulled dpf and sent to be cleaned had to replace because it was cracked sent to hino to have regen system reset truck ran a week and started the issues from above
Could the whole issue be the exhaust flap out of adjustment that's located just before the dpf system
