I have Chevrolet Captiva and for last 2 months I am experiencing some strange issue that on the highway, once my car reaches 90 km/h or above, after a few seconds it fails to accelerate. If I restart the ignition while running, the problem gets resolved. However sometime this issue doesn't appear. I checked my turbo and throttle body and there is no issue with them.
No check engine light at all. Any suggestions?
