I have a 2012 Ford Transit Connect. Gas powered.
When I accelerate, it shifts fine and take's off fine. When I get to 45, it slows down. If I keep my foot on the gas while it's slowing down, it will keep slowing down till I let off. When I let off the gas and accelerate again, it will get back up to 45 and slow down again. If i keep doing that, it gets worse, but the engine never shuts down when I idle or stop.. The wrench light never comes on either. Only has 117k on it. Never had issues with it until now.
