noticed that my cars idle was going up and down up and down rapidly, thought maybe it was a vacuum leak or something but i looked under the hood and i left the cap off of the water so i thought oh maybe thats what was wrong, well i went to work the next day and my car just died, had it towed, its gettin spark to all cylinders, no vacuum leaks, its getting gas, i checked the ecu and it looks good, it was blowing a fuse but we fixed it, now idk, would maybe a cas or something cause this?
