Welcome to the site Mendezfa. It could be a few things, and it would be helpful to know a little history of your vehicle. How many miles? Are you the original owner, or do you know what maintenance and or modifications have been done on it? Our cars are now almost 10 years old, so eliminating any recent repairs or general maintanance will help w/ a cyberspace diagnosis. Do you have a check engine light on? Can you get codes read and report them back here. I didn't mean to disregard your question on the intake, but you need to remedy the driveability issue first.
