Enhance Your Engine's Performance with Standard Motor Products AC158T Fuel Injection Idle Air Control Valve Review

Affordable, works great. Stopped a roaring "vacuum cleaner" like the noise I got every time my truck was idling. My old one was 17 years old and had run 175,000 miles, that was cleared up immediately.

How it worked better after fitted. Run the OB-II sensor, reset everything else, both work much better now. Although there should be instructions for installation after installation.

Perfect fit. I can't say that this solved the high idle problem I had on my 2003 Ranger 3.0. I bought a few other parts that will contribute to the idle problem. The last piece was the air mass meter. After installation, the battery is disconnected and the car works like new.

This product helps solve the external problems we have, it has a screw on the end, it requires a square nozzle, you can adjust it until it works smoothly, and a lower idle screw on the throttle so the idle speed is 900 rpm. It runs smoother than Idols and behaves as it should.
