1999 Ford Ranger 3.0 Flex Fuel Automatic Transmission 2WD Single Cab 121,000 Miles.
My Ranger has had really bad pinging issues when under load and terrible acceleration. Going up hills was treacherous.
I was driving around earlier this Summer and got a CEL for P00153 related to my O2 sensors. I am not a mechanic (famous last words) but attempted to remove the O2 sensors myself after getting the loaner tool from Autozone and three replacement Bosch sensors. I started with the passenger side and didn't get further then cutting the wire before I decided to bring it to the shop. $150 for removal and replacement of all three sensors was totally worth it since they were most likely the original sensors.
Prior to taking it to a shop, I drove around with the cut wire and didn't immediately get a CEL. I probably drove it around three or four miles before the CEL popped on. On my way to the shop, I noted that the pinging and acceleration was gone. The truck was taking on hills like a champ, I was able to accelerate easily on hills without pinging from the engine. I even reached 75 Miles Per.
Once I got the oxygen sensors replaced, the truck ran a lot better with less pinging and better acceleration. However, it felt better with the cut O2 sensor wire. Is this because with the cut wire the computer was dumping more fuel? My diagnostic tool shows negative long term fuel trims at idle (around 4.7) but on heavy acceleration it leans out even more, usually negative 11.7 plus on both long term fuel trims.
I plan on replacing the following items as part of a valve cover gasket replacement/tune-up project and want to know if there is anything else I should replace since all of this stuff is original to the truck. I already did a new MAF (it was a cheapy), wires and plugs (not cheap), ignition coil (cheapy), and IAC (also cheapy). Also, advice on this issue/general life advice is appreciated.
