Strange issues with ranger, pulled codes, not sure where to go next.
Here are the codes: P0231, P1000, P0133, P1131 and P0171. My truck has 198k miles on it. Should I start by changing the O2 sensor? And I have no idea about the P0231 code... any advice? Symptoms include rough idle and truck doesn't stall out but when driving and clutch depressed coming to a stop, the AC compressor cycles rapidly and the truck sounds like its going to stall. Truck is a 2000 xl 2wd 5 speed Thanks.
