My wife's '07 tahoe just had a check engine light come on. I hooked up my little code reader, and it reads P0121. Website says throttle positioning sensor.
1. where can I get one, and how much?
2. where is it located on the vehicle?
3. If I can purchase one, should I exchange it, or are there potentially more issues at hand?
Please advise, I'm out of town for the week, working on 29 palms MC base; my wife needs a car with the kids and all. I have about an hour in the evening, if I drive home, to install.
Also, she wacked her passenger mirror against the garage door. How much am I lookin at for the LTZ pwr. mirror (w/ blinker,)Charcoal paint color?
