recently added bbk underdrive pulleys to my cobra,,,car drove fine,, added bbk twin 62mm throttle body the next day and it feels like a totally different car,,,i can feel a lil extra power when i get on it but when idling the car just dies or idles really low,,,,,,also the gas pedal has a totally different feel,, its really stiff then right when u get past that point it is just like drooppin the clutch at half throttle............anyone else have these kinda problems? what cani do to fix?

I am not really any kind of expert, but I doubt the pulleys are your problem. I imagine the throttle body is letting in too much air and there is nothing there to tell the computer to change the fuel ratio. Did you change the maf? Check with someone who really knows, but you probably need a tune at the least, and probably a new maf with a possibilty of new injectors to go along with the new throttle body.

i really doubt you need new fuel injectors for just a throttle body, why did you get a twin 62? isnt it a stock single? why woud you do that?

no,, stock is a twin 55mm. i just figured, why not get more air to the engine..i have to other bolt ons so i added this.
