I know this is your very 1st post but you most definitely should have read through the Tech Forum Rules. Particularly this portion...

Common or Repetitive Questions
Be sure you've done research on the question before you ask. This site has been around a while now, and most of the basic questions and topics posted by newbies have already been covered here and in other DSM resources. Nobody wants to answer the same questions over and over again. We've put together a list of links that should answer 95% of all DSM questions you might have in one of these areas. Read through them before posting a question:
-Frequently Answered DSM Questions Forum
-Forums Keyword Searches
-How to Use the Search Feature Effectively

Had you done the above you would have rendered a TON of information thats been previously posted by DSM'rs from the last 8yrs this site has been around, particularly this thread Post your sputter, mis-fire, buck, stutter, etc...

Welcome to the site. You'll also notice that in the Tech Forum Rules link I sent theres a bullet that mentions updating your profile. Even if this had been a unique issue thats never happened before how are we supposed to help you when you haven't even filled in the info on what type of vehicle your even driving?
