Hello, does the check engine light turn on when this happens and then go back off or does the light stay on?
About how long has it been doing this and has anything done to the engine, any parts replaced recently?
Thanks, ***** ***** hard on a flat road does it do this then as well?
You mentioned it had 130,000 miles on it, if the spark plugs have never been replaced I would recommend doing that at this time, the spark plugs may be breaking down under load,.
