Driving a 2007 Chevy Aveo, about 80000 miles.
A couple of weeks ago we had a pretty hard storm. My Check Engine light came on, and I had the codes checked:
A little bit after having the codes read, the light went off, and I thought nothing of it.
The other day we had another hard storm, and the light came on again. Codes read again, same codes. Now, though, the light is staying on, and when I start the engine, it revs a couple of times, from 500 RPM to about 1500, then down again, then it settles into place. When the engine is cold, acceleration from a stop is weak, but once it warms up it seems fine. I’m not in any way mechanically inclined, so I have to admit my guess could be far off, but from what I’ve read it sounds like this is related to the throttle position sensor being faulty. But I’m open to advice on other ideas.
FWIW, AutoMD says this is a 100 dollar fix, including labor. Not so sure I buy that, but I can come up with 100 bucks. I just want to know if it could be something more serious.
