Sounds like your A/F ratio is off and your computer is trying its best to adjust. This is a common problem if you have an after market intake. Your car is probably running lean as well, but this is something you probably will not notice while driving. You will either need to get a tune to account for your intake (I recommend trifecta) or go back to your stock intake. Also, check to make sure everything on your intake is secure and that you are not allowing air to slip by... this will also mess up the A/F ratio....

i have a trifecta tune. i think it might be my stock downpipe cause there is restriction or something with all the mods i have added to the car and i have checked everything to make sure its tight. its all good to go. it doesnt do it everyday i start the car. just usually on cold mornings. ill take a vid tomorrow morning and try and post it up. P.s. i have a downpipe on the way and im hoping that will fix my issue.
