When I drive my car sometimes let's say in 3rd gear and slow down using the brakes while coasting it on neutral the car seems to to thru a very low idle at about 2 or 300 rpm and I have to try and keep it alive by accelerating it. Also sometimes while on neutral on a standstill it randomly shuts down. I suspect dirty injectors. What have you guys used that works? Sea foam? Chevron injector cleaner? STP?

 

Why not just replace the injectors or take them out and apart and actually clean them?
