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?
