95 Ford Explorer code 998, 113, along with ABS light

[Ffranzwa]

Hi everyone. I have a '95 Explorer and the check engine light, as well as the ABS lights have been on for awhile. Lately, I replaced the hub assy on both fronts due to excessive noise, but also hoping the ABS light would go out (no luck). Today I decided to pull the codes and I think they are 998 and 113. Any suggestions on what to look for? While replacing the front differential, I noticed that the ground strap behind the drivers wheel has rusted through and the passenger side doesn't look great either. Could this be the cause of the fault codes? Overall, the truck runs good, with exception of slightly high and eractic (1000-1100rpm) idle and the 4x4 light flashes occasionally. Any help?

I believe the code 113 is the IAT (intake air temp), possibly also causing the other code, 998. I could be wrong. I was looking at codes on another website.
