Q: Can resetting 2014 Chevy captiva computer stop the reduced engine power

Hi there. Unfortunately, this is a very difficult question to answer since we don’t know which codes are showing up during an OBD-II diagnostic exam. However, what the local auto parts store probably did was a code scan and not a full code download. There is a huge difference between the two. When a problem is discovered by a sensor, an error code is created and stored in the ECU. This helps a mechanic determine what is causing the fault and make repairs to resolve your issues. However, resetting the ECU and clearing the codes won’t always resolve the root issue. The only thing this does is reset the ECU to allow sensors another opportunity to determine if faults occur. The best way to have your cars hard to accelerate issues properly diagnosed is by having a professional mobile mechanic complete a car is slow to accelerate inspection at your location. This will allow them to download all stored error codes, clear those codes with a professional digital diagnostic scan tool and pinpoint the root source of this issue. If an ECU relearn is recommended after this inspection, that will be verified by the mechanic that comes to your location. That would be the last thing I would recommend having done, as your issues might be mechanical or electrical in nature that need to be fixed.
