Van always starts fine, but after awhile it starts to bog down, almost shut off. I can pull over turn key off and the restart the van and it does fine. But does this all the time. There are no codes except 02's heater circuit to high.
Any ideas to help narrow this down?
I get a 7.34 on the MAF but does not have one.
