The car does it after it has been sitting for a few hours. It will go for 30 secs to 1 min. Any ideas?

Ive been having the same issue since i had my ft installed. Could be coilpacks, spark plug gap, primary o2 sensor or maf.

Could also be a vacuum leak. I doubt coil packs or spark plug gap as it doesn't appear to be misfiring though it is possible if they are giving a weak spark. I would start by cleaning the maf
