I have a 91 Explorer that has baffled me. It idles high when warm, it stays steady around 1000 rpm after I adjusted down as low as I could go; before it was about 1200. Also it is getting pretty bad mileage. It use to get 15-16 around town. Now I'm getting 12. Also there is a pretty strong exhaust smell when its idling. It will occassionally throw a CEL for code 41. So the computer either thinks its lean or that the O2 sensor isn't working. I've replaced the O2 sensor already with no effect. I've tested the TPS, temperature, and the MAF sensor. I can't find any vaccum leaks, and the FPR and the fuel pressure is good. It all seems fine. This all happened around the time after I replaced the fuel injectors. I just don't see how the new injectors could cause a high idle, a code 41, and bad mileage. What do you think is up?
