The check engine light would come on only when I was driving fast on the freeway and it would come on briefly for about a minite and then it would go out again. This would happen 3 or 4 times on an hour long drive. At night sometimes the lights would go out for two seconds and then come on again. This was very scary especially when driving on the freeway. I had a fuse fixed at mazda when the van wouldnt start and ever since Ive been having other electrical problems such as the sterio stopped working as did the inerior light. Then the engine light and the headlight problems. This van seems to be just one problem after another.
