Question

My Buick Rvz when put in park idols up really high as if I am pressing the gas. So I went to Advance and put it on the testor and they recommended the fuel injector sensor. Where is that located. It also will take off on it's own when I let my foot off the brake. What do you think. It's never gave me any problem besides this one time and I have 170,000 miles on it.

    There isn't any "fuel injector sensor," so that advice is wrong. You haven't told us whether the check engine light is on, but with the mileage you have, I'd be suspicious that there's carbon accumulation in the throttle body and it's hanging up the throttle or it's fouled the idle air control (IAC) valve on the throttle body. Either way, it needs cleaning if there's carbon accumulation in the throttle body.
    Three things we like to know:
    1. Which engine do you have?
    2. Is the check engine light on?
    3. If it's been scanned, which codes are present?
    The check engine light indicates that the computer has detected a malfunction in the engine/transmission control system and has diagnostic codes and data stored which would be essential in diagnosing the problem.
    A technician with a scanner can access the diagnostic codes and data and then be able to give you a diagnosis.
