my car seems very different from the first night i got it, it seems a little slugish now, and it is definatly a noticable difference because even my friends noticed a difference from the first night, and recently i have even been puttin in 93 octane is there anyone else who has had similar problems, and if so how can i correct them.

i am definatly going to be putting in a cai, headers, and exhaust but i was just curious of why it is different

are you sure its sluggish? or are you just geting used to the car? is your mileage down?

could be the humidity levels or particular fuel.... check the oils (engine transmission) too
