Buddy of mine ran a scan tool on my 03 f150 4.6 XLT and code po113 showed, think that's it. Looked into it and I found it has to do with the iat circuitry. I checked with meter, 4.6 volts and did the omhs test. I believe all is fine there. Does anyone know if a bad sensor would have or use the same code. The guy cleared the code and has not it never came back,code. Engine light never came on just really bad gas milage. Also if truck idles at 1000 and slowly lowers to 700 rpms is that normal or high?
