[12gauge]

My 93 K1500 Is Pulling Code 35 - Iac Error. I Replaced The Iac Last Year So Im Not Sure If The Valve Is Bad Or If Something Else Could Be Throwing This Code. The Truck Is Also Throwing Code 44 (o2 Sensor Lean) But My Truck Is Running Very Rich And Only Getting About 8 Mpg. I Think The Ecm Is In Limp Mode. What Should I Do To Get The Ecm Back To Normal?

I Need Advice!!
