it sounds like you have either a block or a restriction in your intake or fuel line.

Do you have to floor it when your starting it? Does it only chug when your on the gas?

Since your not getting any codes the only thing to do is first check the air filter then get some intake cleaner and spray it in your intake hose and your throttle body while your keeping the rpms up to keep it from dying. It sounds like that is what your problem is.

[00stang]

i thought something with the intake but u know i'm the inexpierenced one lol but where would i get intake cleaner if u don't mind and ne brand to use and it only shift when i let off the accel. while doing this and when it starts to die i can pump the gas to the floor and back and it jusat keep going down till dead

sounds like dirty maf or air filter, or iac or tps as well. or an intake vacume leak

[00stang]

ok srry i not god with jargon plz speak un technical lol wut is MAF,IAC,TPS

[02ponypackage]

check your lines...clean ur filter and see watsup with your spark plugs....maybe the car just needs good tune up all the way around...fuel filter as well while your at it....i changed mine and my gas is a little better

[00stang]

oh i should have said this i gave it a tune up after i got it new plugs and all and i have changed the fuel filter 2 times i think it might be my lines also cuz it ran great after i put the booster and injector cleaner and water killer/ cleaner

[02ponypackage]

well u dont really need to change the fuel filter twice unless you have a lota miles...make sure u put the filter on rite...the flow direction...

[00stang]

well i had placed first one before hand when i tuned up and second one after they said i had water in tank i was wondering do they have 2 fuel filters i know older vehicles do but not sure bout these

[02ponypackage]

99-04 = 1

[00stang]

kk thanks i was wondering bout that but neway ne other ideas on wut it could be

[GreenFaleen]

you get gas from the same place everytime? could be they have water getting in their gas. Also Get electrical cleaner and clean the MAF like they said.

[00stang]

wut is the MAF plz tell me and ok i appreciate wut u guys telling me ne thing else wut i'm gonna do is do all of these at same time

[GreenFaleen]

oh I thought they explained it my bad. MAF (mass air flow) regulates airflow into the engine it is on your intake about mid way up. If you have a stock intake it is in a little box covering you have to take apart.


thats the best pic I could find that is one with a CAI. but the thing I circled and the piece it is screwed into is stock just unscrew it and spray it with a electronics cleaner and spray the sensor inside the little pipe it is connected to and make sure you give it time to dry well

[mustang1072]

MAF - mass air flow... make SURE you dont have anything blocking your air consumption! i had a similar problem with my truck i had no idea what it was till i started to take apart the top of the block and realized i had this peace of foam wedged in my intake manifold

+1 i had a seriously bad tank of gas and i noticed bad running conditions ive stopped going ot the same gas station and all is well. i went and complained and they said basically go fuck my self

now, how the hell did you get foam in your intake?

[97stanger]

now, if your running BP gas, thats the problem. well, at least it was with me. Everytime I put BP in my tank, it RAN like a tank. (so to speak) lol. then when i put shell in it...it runs like a dream. lol

shell is the best gas u can get they put in additives that help keep your engine running clean and in top shape

try changing the fluids in it also. remember mechanics are not infalable. they can screw things up sometimes. and sometimes things do take a little while to come up. also check your tank for any tears or little cracks where water could be getting in to it. and i would get a compression test just to make sure.
