Review on 🔧 Optimized Idle Air Control Valve by Standard Motor Products - Model AC253 by Cody Mckechnie

Red flag price but I went for it. Had trouble idling at 500rpm in cold weather. I was tired of hitting the old IAC valve with a broom to get a >800rpm cold start at idle. . Significant improvement at idle, consumption per gallon is also monitored. UPDATE: set to one month, now the continuous messages P0171 and P0174 are issued daily. Would rather not turn off the check engine light on EVERY START
