My husband has a 2009 Chevy Aveo, he’s had several issues lately, split radiator hoses, an oil pan issue and now he says it’s decelerating when he’s driving on the highway, the engine doesn’t rev when he presses the gas pedal, we can’t afford a new car but he’s afraid to drive an iffy car through the winter on a somewhat long commute, has anyone heard of this happening and have any thoughts or suggestions?
Are there any check engine or other warning lights on?
This has to be an intermittent problem (can’t be decelerating all the time). Are there any conditions that cause this to happen? hills? turns? any warning lights?
We need a lot more information in order to even hazard a guess. In addition to the questions posed by Barkydog and BillRussell, I would like to know if the OP’s husband has checked the dipstick, and–if so–what the oil looks like.
If the oil has the appearance of a milkshake, that would be a pretty strong indication of a breached head gasket. A blown head gasket can lead to over-pressurization of the cooling system–thus causing split hoses, and it can also lead to leaks in the oil pan gasket. In short order, it can also destroy the engine, so this is something to investigate immediately.
It IS an Aveo… not exactly know for its ACCELeration!
Seriously, we need more information. There are so many things that can cause this. Some simple, some really bad.
Yes…more information is needed. The last time this kind of thing happened to me…it turned out to be a bad TPS (Throttle Position Sensor).
Or you can take your car to a mechanic for diagnosis. If you don’t have anybody in mind you can look for good specialists here: https://www.hirerush.com/anywhere/service/auto-repair-services
Hope it will help.
Nice try Stenly. We need a few more flags and your post will be gone automatically.
Why? I just wanted to help…
It’s called SPAM Stenly. Read up on it.
I didn’t mean to spam. If it’s not useful for the owner of this thread then I’m sorry.
Your Aveo utilizes a drive-by-wire throttle system.
This means instead of having a throttle cable from throttle pedal to the throttle body, your vehicle has a throttle pedal position sensor that sends a signal to the computer. The computer then takes that signal and depending on the throttle pedal position, operates the electronic throttle body
So the problem might be caused by a defective throttle pedal position sensor or the electronic throttle body.
