thanks for your help! i mean ive heard that the worst it can do is make ur CHECK ENGINE LIGHT COME ON! but i dont know, i dont wanna risk that sh*t! but thanks

Of course they don't work.

The theory was on firmer ground in the Eighties, when air flow sensors and fuel injection computers were just becoming common. The air sensor measures the air, and prescribes how much fuel goes in; fool the sensor with a simple resistor and it changes the mixture/power.

These days the computer would adjust the fuel back to where it needed to be in seconds, based on feedback from the oxygen sensors, downstream from the engine. Then it would check the sensor's overall resistance, and record it as a fault, and throw a CEL. End of experiment, $20 down the drain! :mdrmed:
