Error Code Overload

[IMP]

I have a 1995 Mustang with a V6 and am experiencing erratic idling. Half the time when stopped in drive I have to use two feet because it will stall. Check Engine light is ON and the following codes re-appeared after clearing:

P0113 IAT Sensor 1 Circuit High Output
P0102 MAF or VAF A Circuit Low Input
P0174 System Too Lean (Bank 2)

A year ago I replaced the IAC Valve and it worked great so recently I pulled it and cleaned it but it was already clean and this had no effect. The exhaust smells as if the engine is idling under fuel-rich conditions. Given the three codes, can anyone recommend a starting point or shed light as to what may be going on?

Sounds like your MAF is dirty or shot if the system thinks its running lean, but smells rich.

Cleaning your maf is a good place to start.
