My car starts but then dies out. We thought at first that maybe the tension on the belt needed to be adjusted because it felt a little loose. So while trying to adjust it we learned that the coil to adjust it was broken, so we replaced it, adjusted the tension, but still it dies out. Could it be that my timing needs to be adjusted or could it possibly be the fuel line, because I had been putting 87 and 89 fuel grade instead of what it says to put which is Premium( 91).
