Hello
I have a problem with my van. It's starts well and drives good for about 10-15 minutes. Then it won't accelerate anymore. Even on neutral revs won't go up. I have to turn engine off and back on. Then it drives for a minute or two fine and cuts off again. I bought F-Super Mk3 fault code reader. It connects fine but there is no errors apart one - P1631. It gone away after I replaced the battery but the van still is not well. Next I replaced an throttle pedal but stil no joy.
There is no smoke, no errors, engine management light is to on.
Any ideas what to check next?
