Okay my Mazda takes a while to start when it is cold and it burns a little oil I know this is telling me it time for a rebuild (Twin turbo time!!!!) but i am missing emission controls because of an electrical fire could that be misleading me to think I need a rebuild car runs okay when you get on the road. Sorry bout long post.

 

Details...year car? Stock engine or swap? Carb or EFI?..etc...give us a run down on the car and when was the last time you remember this NOT happening in the cold?
