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

I ordered this product without a case and only the last 2 months it doesn't work I have the same problem again I don't know if you can still have it no guarantee I send back very disappointed. Hope maybe it was damaged, maybe they can send me another one

I bought this for a 2001 For Expedition with a very loud hum coming from the air intake. I read on the forums that this device was the culprit. It worked like a charm. I highly recommend this device for this problem.

Bought for Expedition 2004 with 5.4 engine, fits well. Do yourself a favor and fit the included gasket to the part prior to installation. Fixed an engine stalling issue at a stop sign that is very common on Triton engines.

Paid $36. Worked two and a half months. Now we have to replace this scrap. waste of money and materials. This simple mechanical device shouldn't just fail after 2.5 months. My original has done 172,000 miles. I think I could tell myself I'm only taking it off for 2 months, but I'm not.

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

I bought this thinking it was my idle problem. It wasn't a problem (vacuum leak) that has since been fixed. I've had very strange idle issues with this unit installed, starting and stalling when cold, slow return to idle, high idle etc. I reinstalled my old part after a quick cleaning and all is fine. This is a type of PITA that fits my 1998 F150 at 5.4. So if I had to switch again I would buy an OEM product for just my 2 cents.
