2005 Toyota Sienna 6 cyl Two Wheel Drive Automatic 65000 miles
I am testing and bought a gas saver and it is connected from the brake booster to engine intake. After 4 months with gas saving check engine light on. I bought a scanner and I eliminate the light. I saved gas from 23 to 32 mpg.
My question is does it will damage my engine if I continously use this device?
What will be the effect of this gas saver to my engine in the long run?
