When driving on the highway, reaching 60mph, then dropping down to 50mph the sevice engine light comes on. I had the codes checked and the recomendation was to change the ERG valve. The valve was changed, the same light comes back on at the same speeds, with the same code. No noticeble change in the engine. It is an electronic valve, no vacume hose. The car has 150,000 miles We should I look for next?
