What do you think the problem is?
I have a 1998 ford ranger 2.5 and the truck runS real rough at idle. I have 2 trouble codes p0141 , and p0171. Just recently another code has came up p0303. I cleaned the maf and the truck ran great. The next morning i got in the truck and it ran fine for 5 minutes then ran real real rough.. I erased the codes an now the only codes left are p0141,p0303. I know that po141 means that the o2 sensors are no good. Code p0303 means cylinder 3 misfire. I checked the spark on both spark plug wires on cylinder 3 and I have spark. Do you know what the problem can be besides the 02 sensors? I will really appreciate all the help... Thanks...

how did you check for spark? did you check the resistance on the wire? did you check the plug? your definitely not getting ignition on cylinder 3 and thats why your get an o2 code.
