tbs sensor 03 saturn vue 3.0
 

i just got everything running great on this car and i notice my tack that my rpm would move just a little bit once and while , it runs at 700 and runs pretty smooth. i was going to put a tbs sensor on , the cost is not to bad, an i did read that one of the signs is movement on rpm could be tbs sensor not plugs or power packs what do you think thanks

It's a 13 yr old vehicle.
If you just got it running and there are no SES codes for the throttle pos sensor, why would you want to mess with it? Try some Techron fuel system cleaner.

Do not fix what is not broken or you will be left with no money for petrol to drive the thing
