I have the following situation.
2000 kia spectra
After driving for a while (car is sufficiently warmed up) and coming to a complete or near complete stop, my vehicle will backfire out of the tailpipe for about 5 seconds (not long). It is not loud or very noticeable but if it goes on for a couple of seconds the idle will drop and the car will sputter. It does not do it all the time but here the situations where it can happen:
1. Cool-cold days
2. Cool rainy days (never noticed while warm-hot outside)
3. When complete stop or slowing while going up a hill.
