Chevrolet Aveo, accelerates on its own. Posted by manual-mecanica
Hi everyone, my car keeps accelerating on its own. I've already replaced the IAC valve and cleaned the throttle body, but it's still doing the same thing. I'd really appreciate any help, and if anyone has the workshop manual and could upload it, I'd be very grateful. Thanks in advance.

Hi Victor, question: Is the engine revving too high? Or is it like the engine is cold? If so, have you tried changing the temperature sensor? First, check if you have any resistance readings in ohms. I don't have the manual, but there's a program called Autodata. I'm trying to get it, but I don't have it yet... if you manage to get it, it might be useful since it shows some relevant data.

Best of luck.

Look, the car revs up at normal operating temperature if I stop at a corner. When I accelerate again, the revs drop. There are no warning lights on the dashboard. It's more noticeable when I press the clutch. Also, I recently disassembled the throttle body again and found the hose connecting the air filter to the throttle body is broken. I don't know if this is related. Where is the temperature sensor located? Thanks.

It matters if it has a flow meter before the air intake; if not, it doesn't matter at all. Does it have a cable throttle or is it electronic?
