Review on 🚀 Upgraded NewYall Idle Air Control IAC Valve IACV for Enhanced Performance by Marley Woods

Failed the 1st run. I was very lucky that there was a bend inside the manifold for the sensor, otherwise the metal and plastic would have gotten into the engine. On the second start, my engine kept stalling. Here's your problem! Who would put a very thin, brittle, fusible plastic into an area that would heat up enough to melt the ring between the metal head and the sensor body? Shit! that sucks! 2004 Jeep Grand Cherokee 4.7L V8 is way too much for this lousy gauge! Go ahead, waste your time, effort, money and hope you don't break your engine. Although very easy to install.
