1st Field Test of AC_VeggieSteamSmacker Hydroxy generator on my ’96 Ford Explorer. Worked great, so I decided to do 2nd test of adding hydroxy to the air intake. I created a “check engine” light by opening the air filter housing. After adding hydroxy to air filter input, the check engine light turned off ! Also, the RPM’s dropped lower and engine ran smoother. I noticed the exhaust seemed cooler and there was a small trickle of water coming out of the exhuast pipe and no odor from the exhaust that I could detect.
