I am looking at replacing my throttle body. I was getting 19 mpg (highway), low power, eratic shifting, stabilitrak and traction control errors with a flashing CEL that would go off and not set a code. Sometimes it would set a P0300. I cleaned the Throttle body and it cleared right up; for a half a day. I got up to 25 MPG highway (Carlsbad, NM to Roswell, NM, it's 90 or so miles 70-75 MPH most of the way). On the way back, within a few minutes of starting back, it set off the error messages again. The next day, today, I went another 90 mile trip. It set off the messages and power and shiting were terrible. I pulled over at a rest area removed the snorkel and cleaned everything again. It cleared right up, mileage went up, and shifting was perfect. I know the throttle body didn't get filthy dirty on the first 90 mile trip. I can't think of what can be wrong. Unless my manually moving the throttle body butterfly has something to do with it. Opinions?
Hey Brian, some vehicles require a sensor learning trigger from a scan tool after a new sensor is installed. Often a 5 minute battery disconnect can initiate the learning process. In this case for the Acadia it did not require a reset. Thanks
How did you come to this conclusion? I have the same car, and when I’m between 20-40 miles an hour, it stutter. I’m guessing it might be the throttle body sensor.

I would just replace the throttle body. It’s a cheap easy fix
NO NEED FOR DISCONNECTING BATTERY?...I WAS TOLD REPAIRS LIKE THIS NEED TO DICONNECT BATTERY TO RESET COMPUTER....NO?

Did you ever figure out what the issue was. My car is doing the same thing
Did you have to reprogram after the replacing?
Hey, you don’t need to reprogram. After replacing you should be all set.
Same !
What air code was it sending you
I don’t remember the exact code, but the description from the code reader at autozone indicated throttle body issue.
