i wanna try puttin back on a stock tb bc my car is runnning to rich and i dont have enough money to get a tune. but my friend has a 97 tb he will give me so will it work

Not sure if it would work, but by putting a more restrictive TB on would allow less air in the cylinder. Less air and more fuel, making it run even richer.

ya i guess thats true i dont no y i didnt think about it i guess i was gettin to excited on trying to fix my car. i dont no what to do now. the mechanic told me its running rich i dont have new injectors or anything like that so back to the shop

but with a larger tb and stock MAS could that throw off the air fuel ration?

I thought you could adjust a/f ratio with the Diablo? Or do you just not want to do it because you are afraid you will go too lean if you are not on a dyno to tell?

thats true u can adjust it with a diablo tuner but i have a diablo chip and the chip has to be re tuned. which sucks i bought the car with a chip if i had my choice i would have bought the tuner. but well see

But, less air = less fuel too.

leave the tb, changing it wont solve your problem. that diablo chip is the problem. again, i dont know why people buy this crap. the guy before you had a mail order tune. the only thing you can do is retune it. and if your going to do that, switch to a SCT. the best on the market.

why would you want anything less on your car, when it comes to something so vital as your engine and computer tune?

ya if it were my choice i would have bought the hand held tuner but the chip came when i bought the car so ya
