i have a bone stock 86 mustang gt, i put a trick flow intake manifold the hole unit and the problem is that it dont want to stay started at idle. the only thing i think it is that i am not getting a enough fuel or that my throttle body is to small. not for sure what the problem is please give info thanks for reading

Any other mods or changes likeconvert to MAF? If not is your MAP sensor hooked up and all vacuum lines good? Any obvious sucking noise when running?

not that i herd i mean it starts fine and it just dose not hold throttle it just dies when your not on the gas. i mean i am running the stock 62 mm throttle body i think thats the problem but i dont want to buy a new one and thats not it i want to make sure

Just reading on Trick Flows site is says 75mm so that may be it but not certain. If it stays running giving it gas, does it have a rich smell from the exhaust?

no it's not the problem , your entire stock induction is adequate for up to about 300 hp

i'd say you need set the idle,tpsand reset your computer. thats assuming you truly don't have any vac leaks, because if you do...thats the problem

mustang freak

ok i will check vac leaks again and i will try to adjust the idle,stupid qestion what's the best way to reset my computer and what's tps lol.
