Every morning for the last week or so when i start my car in the morning it fires up, idles crappy for a second, then stalls. When i start it back up its fine, no problem at all. This only happens in the mornings after the car sets overnight. I've tried f.i. cleaner and throttle body cleaner and everything else i could find i cleaned. I think the problem is something electrical but not quite sure. Any ideas? I just changed the plugs too so thats not a problem.
