so, after my build the car is very hard to start cold, lots of missing and white smoke, and should run a lot better than it does for whats all done to it, i had GTD nozzles installed from a GM mechanic i know, he popped tested them, but i kno he didnt adjust any of them, or none were sanded down/lapped, and there was a good chance dirt got in them from sitting in the garage for a few months, could this have anything to do with my issues? thanks for info
