K, this is what I am working with... I have a 93 GT .30 over 302, GT40 upper and lower intake and GT40 heads off a 96 explorer, 1.72 roller rockers, E303 cam, 75mm Mass air and Throttle Body with 19Lb stock injectors. She stared running like crap in the walmart parking lot and I limped her home where I found out it was a bad MAF sensor and had to run default with the MAF disconnected for a while till I could get a new MAF sensor. I was at a junk yard and it looked like the 01 V6 explorer had the 75mm intake and it has 19 Lb injectors on it (I do not know for sure the Throttle Body size cause Ive never owned one) so I grabbed the MAF sensor off it and hooked it up to my car. It sounds and feels like its running fine but my check eng light is still on. I have a Equus 3007 code reader and it was throwing a code 9854 twice and I cant find a ref for that code anywhere online. So my question is this, does anybody know what that code is or where i can look online to find it?

They don't have any 4 digit codes on the 93 mustangs, are you sure it wasn't a 98 and a 54?

It every well could have been. I havent spent to much time with fords that had computers, mostly just Carbed. I just started messing around with fuel injection.
