Anybody hear of Dixie Caps (http://www.fuel-economy-tune-up.com/instructions.html)? iv been seeing alot about em sence the gas price went above 3$ a gallon hear. and they are a reasonable price to. i wonder how well they actualy work, or if any of the electrical gurus hear know if they actualy work.
I'm gonna call :bs: on this one. Sure a capacitor will smooth the signal to the injector but what is that going to do for you? All the injector cares it that the signal is over the voltage required to actuate it. I don't think I'd spend the money on this.
I dunno you could put one on your light switch to save electricity. I am with you they would garentee it if it worked. Not say may improve gas milage and emmsions.
