Hey guys,

I have a 2011 Ranger 4x2 with the 4L engine. Today I got a check engine light with a P0303 code. A search on the net shows that to be a cylinder 3 misfire. Truck is under warranty so I will take it to the dealer.

Would a K&N cold air intake (the whole kit) and a Gibson dual exhaust be connected in any way to my check engine light?

Thanks,

Rob.

 

i dont see how it would be related at all

 

Just to play it safe, I would put your stock filter back in when you go to the dealer. It might not matter but I would just play it safe so they have nothing to complain about.
