okay WTF

[Orange Stang]

whats wrong with my GT... Here goes...

The problem that I'm having is that sometimes when I don't need to press the throttle completely down, and only want to accelerate slighty, the car completey ****s it's pants and has no acceleration. thats the easyiest way to say it. it like gurgles weird too. The only way to fix it is to press the pedal down farther to almost full throttle then it really gets up or tap the brakes and let on the throttle again, then its fine...

Ryan suggested it may be a bad TPS, Haynes said the rear brakes being bad could do this...

my car has one leaky injector, could that cause this. Also could it be fuel related. im sure my filter is nasty after 16 years probably. Its gonna get replaced anyways...

Could it be the custom tune?


so many things...

 

[Orange Stang]

I want to mod the car more but not knowing if somethings fucked is keeping me from it. It could be the TPS im thinking but i have no idea....

Check engine light on ? if so what codes is it throwing ? how many miles on the car ? have you tuned it up recently ?

id start with the tps, my car had one poop out and drove like shit, easiest way to check for it is to plug in a scanner and watch the live data and slowly press down the pedal and look for a smooth voltage change from under 1v to about 5 volts at wot, or just replace it, their pretty cheap and grab a $5 fuel filter while your there, your car will thank you

throwing no codes at all. engine is out of a 30K mile bullitt. it was doing this with the old NPI engine as well after i got it tuned. before, i dont remember....

 

[2002BLGT]

could be fuel pump , mass air meter , any number of things , definitely sounds like its not getting fuel to me though

 

[MadStang]

datalog. Your problem will be apparent.

 

[Orange Stang]

im gonna check the TPS sensor.... and change the fuel filter...

if not its going into the shop.... we'll figure it out...

id like to have the cams put into this thing but still worry....

Throwing money at the car when you don't know what the problem is, is the worst idea ever.

You have a tuner right? Do you have a laptop? If so DATALOG AND FIND THE PROBLEM YOURSELF INSTEAD OF SPENDING $$$$$$$$ AT A SHOP.

Mine used to sputter at part throttle before I changed the fuel filter.

 

[Orange Stang]

I don't have a hand held tuner.

I don't have a hand held tuner.

then how are you planning to run cams?

 

[Orange Stang]

Custom tune? Lol. I'll get one when the time calls Haha

the times going to come quick when your car stalls everytime you put the clutch in or come to a stop. Good luck.

well hopefully ill be doing the install at the tuners shop so we can get it tuned right then. Ive always been a bigger fan of custom tunes rather than a handheld tuner.

idk..... If i need one ill get it

handheld tuners are way better than a chip if that's what you're referring to. I have an 87 octane economy tune, 91 economy tune, and a 91 performance tune all at the press of a few buttons. And I can adjust the idle rpm etc to my liking as well as figure out issues with the ability of datalogging. Just saying it's an invaluable tool.

 

[Orange Stang]

i agree with you there. ive been looking up SCT stuff and yea... I feel like a tard now...

and you can get one for cheap.. I got mine for $50 and it was locked but since I got a dyno tune, my tuner unlocked it for free...

do simple things, one you could change the fuel filter if you havent already done that. That will cause a bog. also pull your MAF sensor out and get some MAF cleaner from your local parts store and clean the prongs off. Dirt can accumulate on these and could cause a misreading in air/fuel ratio. Also this will not throw a code as well. Its worth a shot for around $15 depending on what filter you use could be cheaper. I would go wix if available.
