Sputtering loss of power uphill Dakota 2006

Check/replace your fuel filter and check fuel pressure. Scan for codes for other problems.

Ed92626 your right I have the check engine and it threw code p0300 I changed plugs that took that off the codes but both times (with and without new plugs) it threw another talking about o2 sensor failure is it really the sensor or something else giving it a failure?

Where is the o2 sensor located? How can I clean it and check wires

Ed so a freind has the same truck he had the same problem he changed his cat, but he's having the same problem again and well cats aren't so cheap so I wanna know if I remove it and get a new exhaust pipe have it all replaced directly what can I do with the sensors? Since they can't be replaced on a straight pipe, I'd rather change the whole exhuast system without the cats than having it replaced every now and then, but I noticed the sensor so I wanted to know what to do with those if it will affect if I leave them out just strapped somewhere safe
