    not sure why but my car stumbles when punched from a roll. I dont think it does it from a stop but I hardly ever gun it from a stop (tires are pricey).

    anyway. only things done are intake (cone filter)/180 tstat/al104's... headers/tune/3.4 after the holidays. may get the headers for myself for christmas. we will see how much I spend on the wife and son (diamonds/toys get expensive)...

    anyway.

    car has new maf/new plugs/all new fluids (yes ALL)... NO CODES... (I need to clean coolant sensor. coolant is full and topped off)...

    anyway. here is the vid.

    id lean towards the cat then, as it warms up they seem to clog up, little by little it should get worse. or if its broken, the chunks fall out of place and clog the exhaust pipe up.
