When slowing down and braking at a stop sign the engine sputters and wants to shut off, but doesn't actually shut off. Other wise it runs fine. Thanks

Good evening,

This could be an EGR valve stuck open causing a massive vacuum leak.

Is the check engine light on?

Can you verify the engine size?
