Injectors good. Starts fine. Runs great with a load. 7-8 mpg. But idles very rough, when coming to a rolling stop and getting back in the throttle it bucks and shakes and I have seen puffs of white smoke twice. I had the starter replaced a few days ago and this problem appeared after that. Any ideas?
