Chevrolet Spark 1.0

Good afternoon. Regarding the issue, if it's a Chevrolet with a throttle body, it's most likely that it's become miscalibrated. There's a procedure in the service manual for relearning the throttle body, but it never worked for me. I suggest using the Tech 2 tool, which is the most recommended way to avoid this type of problem, as these vehicles are prone to this issue.

Hi everyone! ...it's not the same topic, but it's the same model. Has anyone else encountered a recurring problem with the EGR valve? The first time the check engine light came on and indicated a fault in this component, it was because I was using lower octane fuel. This was fine for a while, but this is the third time the light has come on indicating a problem with the same component. This has happened with two Sparks now.
If any of you have any experience with this issue, I would appreciate it so we can get straight to the point.

Hello everyone, whenever you post a comment about a problem, please include the mileage, year, and engine type (M 300 for the 1.0, 1000 cc - cubic centimeters).
Also, as navlag olugna says, the idle speed at 1300-1600 rpm is abnormal.
