I found this out because one of my customers had a car he claimed would be difficult to start what ever he did. I would go out to it and it would start so quickly I could not even hear the starter motor. After several call outs I got him to show me his starting technique, he put his foot to the floor and turned the key, when I asked why he did this he answered well how else would it start with no choke .
I showed him it would start foot off and he was amazed.
Thanks Guys, much appreciated. Yes, the dealer did say the way, out if it happened, was to floor the throttle and crank it over, so that makes sense. Engine seems in excellent health (40K miles with FSH). Just had new plugs, so that might help; I might upgrade to Iridium / MSD coils. Rich
