after many hours of reading, a change of CVT and engine coolant, a solution was found!
Ended up taking van to stealership and surprise no codes on ECM or TCM and supposedly tech couldn't reproduce ( not possible as it was having its tantrums on way to stealership!) Tech located ripped INTAKE BOOT! Multiple rips in fact. Surprising on a 9 year old van with 198K kms (125K M,) but guess Canadian Winters and exhaust gas recirculation caused break down?
So, $144 for diagnosis, and $173 and change with Trudeau's tax we are hesitation free!
Check your BOOTS people maybe an easy 15 min fix!
