Hi John,
Thank you for the info. I may try warming up the bus more before going. Usually it preforms best if we just start it and go. I’ve noticed that if I let it warm up and then go to drive away it would want to stay. Not sure if these are related problems.
My bus has a new 2.1muffler and CAT and the oxygen sensor is a newer version to match that set up.
Still if just warming up the van solves this problem for now that would be a good thing.
Like your example it seems to happen if the van is just started, comes to a sop and then is asked to excelerate. Sadley this is right at a dangerous busy intersection coming out of my home.
