🔧 Mopar 4861552AC Fuel Injection Idle Air Control Valve: Ultimate Engine Efficiency Enhancer Review

As a result of using this product, I found that my fuel efficiency increased significantly. The valve is easy to install and works great with my performance car. The only downside is that it's a bit pricey compared to other options on the market.

I have noticed that my engine no longer idles at high idle on cold starts and my fuel economy is better. (Not to mention my AFRs have always been rich). This matched my 2005 Jeep 4.0 throttle body perfectly and restored fuel economy and engine idle fluctuations (higher on cold starts or on AC).

I have noticed that my engine no longer stays at high idle on cold starts and that fuel economy has decreased. The 4.0 throttle body is perfect, restoring fuel economy and engine idle fluctuations (higher on cold starts or with A/C on).
