problems please help

[sbarbour]

hello recently i purchased a 2008 cx7 awd.. and i purchased a cold air intake... well lets say the suv ran like crap with the cold air intake... so this am i switched back to the factory intake system.. now the car is running worse... and when i try to place the transmission in reverse it feels like its gonna jump out of the car.. please help i reset the battery numerous of times and still having the same problem...

Maybe a vacuum line was torn or not connected back. Try to retrace the steps you took to remove the original intake.

Yeah, we need more info, and possibly you messed with the mass air flow sensor?

What's the story, did you ever fix this?

Peace!
