Choking and stall on startup
 

So I went to start up my supra this afternoon and it choked and stalled out. I tried it again and it started up fine. Should I be worried about this? I was thinking maybe it was some condensation in the gas tank. It was about 1/2 full and the nights are getting colder. I just recently changed out all the spark plugs for iridium ones and the oil is only about 1000km since it was changed.

What year is your Supra? Auto or 6spd? n/a or turbo? any modifications? What is the mileage?

its a 93 6 spd. I have noticed some slight white smoke coming out of the exhaust with a rich smell.

Any modifications (eg BOV)?

Nope it's all stock except suspension and exhaust.
