I have a 2006 Nissan Frontier 4.0 l with very low mileage. I have a P0300 error code which wont go away. I have replaced the plugs.. some of the coil packs and the maf sensor. The truck barely is capable of moving. It is running very rich and actually set off the co2 sensor in my parkade. When I look at the new plugs I put in they seem fouled already. I am out of ideas. Has anyone else had this problem? I am wondering if it could be a plugged cat? Any and all help is appreciated

I actually had a friend who pulled this code on her Sentra, and it turned out to be a torn intake boot. It could also be the injectors or an air leak on the intake manifold. If those are OK then might have to look at the electrical circuits to and from the coils. Refer to the following page for more information.
