So I have been having troubles with the check engine light for the past month. It seemes that whenever I get out on the highway doing about 120-130km/h for a short period of time that my light comes on. So I changed the fuel filter cause it was time and looked at everything else, but it still comes on. I haven't added or done anything to the car in the past half a year, so what is going on here. Anybody had a similar probler or got some ideas??? Thanks.
