Check engine light on p1151
Hey everyone! Newb here. I had a question about my 95 ranger 3.0. I'm new to the Ranger world and could use help. I recently had the clutch in my ranger replaced and after I received it back the check engine light has come on with a code of 1151. It says lack of O2 sensor switch bank 2 sensor 1. Then it goes on to explain that it could be caused by low or high fuel pressure, a dirty or damaged MAF sensor, a vacuum leak, or bad injector or pressure regulator. I'm not sure if anyone has had this problem before, but if they have any advice would be greatly appreciated. I plan on replacing the O2s on it weather they are bad or not because I think they are still the stock ones. The truck has about 143,000 on it at this point. I was worried that the pressure regulator could be bad but I'm not sure where the fuel pressure is supposed to be at. Mine is at 34-36 at idle and jumps to maybe 40 with a quick hit of the throttle. I have noticed a drop in mileage since I bought the truck about 9 months ago. I used to get about 300 miles on 3/4 tank of gas, and the last I check I was getting about 250 miles on 3/4 of a tank. I have recently done a tune-up on it including an accel coil pack. It also has a K&N replacement filter and Flowmaster 50 series muffler. Again, any help with this would be greatly appreciated!

That is the exact reason that I hate taking my vehicles to a shop. But, I live 2 hours from my parents house in an apartment and my buddy and I ran out of time trying to get the trans out. I did however look the truck over a little better today and found that the vacuum line going into the throttle body from the evap canister was cracked. Kinda hoping that is the problem but am doubting it. I put electrical tape around it for now but will replace it this weekend. Stupid work always getting in the way! lol
