isn't the "cold start" only about a minute anyway? or does it need to reach a certain temp before going to a normal run type? |

The old carburetor ones were probably about a minute. Can’t say I ever timed it. The automatic chokes usually opened as soon as you started driving or even gave it a shot of gas. Modern tunes may go to a certain temperature to heat the cats but again I never really pay much attention. It just simply something cars have always done. Well cars that were running properly at any rate. There was nothing worse than a choke that wouldn’t close when it was cold unless it was one that wouldn’t open when the engine warmed up!

anyway, our car gives a short burst of rich shot at the very beginning but then it targets a lean afr of 15.7 afr or around it
