article that you can do this with you Oxygen sensor. It tells all about pluging the wire, digital volt meter etc but then the question is, how do you adjust it? With an Adjustable Fuel Pressure Regulator? Or what? This may sound dumb, but I'm just not a born mechanic (rather one that learns his stuff day by day).

Also, the article specifies what the voltage should be at wide open throttle. Should I meassure in Park in my driveway or should I measure while driving (sounds like a stupid idea). I need specifics please (like a SQL statement ;-))

Thank for the help guys!

 

Dude, Im sorry but I think you are refering to adjusting the TPS (Throttle Position Sensor) You should measure it in park and you don't even have to start the car. Just make sure the key is turned on, or you won't get any voltage.

 

setting the fuel/air mixture by the O2 sensor is for carburated motors. it doesn't apply to GM fuel injected motors.
which one do you have?

 

Thanks! That solves it. Yep, I got a fuel injected one. Learning one thing a time. Thanks again.
