Default Hard start when cold

Hello all,

Once in awhile, I go to start my bonneville first thing in the morning and it just sputters and stalls. I have to hold the gas pedal down a little bit in order to get the car started. After that it runs fine. This seems to be happening ever since the weather got really cold. What do you guys think?

I personally think it'* your IAC passage in the TB. Remove the TB, remove the MAF and IAC. Seperately clean the MAF filament carefully with alcohol and a qtip, scrub the TB and the IAC with intake cleaner and a brush, paying particular attention to the IAC passage itself.
