cavy's sorta misfiring i was told it was the fuel injectors
and i want to replace them but i might as well put nice good ones in while im at it so im looking for ideas
and just wanted to know if this is a project that isnt so hard to do and i could possably do myself
and im pretty sure if i put performance fuel injectors in there i have to take the car in to get tuned unless im mistaken
please help!
thanks! =]

yep... you'll need to get a tune if you put bigger injectors in...

if you don't have HO Cams or bigger, or if you aren't boosted (which boosted related posts belong in the boosted forum), you won't need bigger injectors.
