Not everytime, but quite often when shifting from 1st to 2nd or 2nd to 3rd my car shakes and kinda sputters. Someone once told me its because of my ram air intake, anyone?

 

need more info on the shaking, but it is NOT your intake!

 

Its like the engine stutters because it affects the exhaust sound too...start stop start again...stutters then goes.

 

is it like ur not getting enough fuel?..sometimes when an intake is install d it will cause a lean burn..try upgrading ur fuel to the next higher octane...as for the studdering..check ur plugs..this happen d to me and my plugs were fried..after changing them the car runs great

 

yeah check the spark plugs and see what happens when u just start the car and just drive up and down your drive way see what happens

 

I know what you mean. My car does that too sometimes. When i shift, say from 1st to 2nd the car will hesitate just a little then go. It just im not getting enough fuel or spark when i initiate the new gear. Im gonna try changing my plugs cuz they're due anyway. Any suggestions? Are the 'universal indexing' spark plugs any good?
