Hi Guys,

I've been having some trouble for a while now. Each time I fill my tank, i hop in the car and turn the key to start it. The engine starts, but it sounds like the system chokes on the fuel and there a sounds almost like the starter out of sync. Each time after that it starts perfectly until the next fill up. The dealer can't figure it out, of course they don't road test it.

I've replaced the TB and plugs, exhaust valve on engine and more that I cannot remember. If you ask it might jog my memory. Anyone have any ideas?
