plz i am really worried about my stang. i drove it home fomr work and it was perfectly fine starting and running like always. came home parked it and went to start it 20mins later and car wont idle properly it is puttering really bad. try to rev it however car woudl not rev properly. now car will just start putter and turn off. what could be wrong?

 

Did you check all your TB electronic sensor (and MAF sensor) connections and hose connections?

 

do you have any mods on the car?
check your air intake elbow if it's fit properly onto the throttle body
Check the connectors around the engine compartment, starting with the MAF sensor (to the left of the air filter), the Throttle Position Sensor (to the left of the Throttle body) and the Throttle Body motor ( to the right of the TB).

do you get a check engine light?
do you have a handheld tuner you can use to download DTCs?

come on, you need to be a bit more descriptive in order to get any help

 

Give us a little more info. Are you running stock tune or an aftermarkert tune. We can help you if you give us a little more info!!!!!!! It is probably something simple!!!!!

Try putting some Chevron Techron in the tank. You might have a bad tank of gas or perhaps you need a new fuel filter.

 

im running everything stock nothing has been done to it, and i have not got ne warning lights or the car showing ne signs of running down everything was running perfect.

 

Could really be a number of things. Start by looking for obvious things in the engine bay, loose hose, clamps, electrical plugs (coil packs and injectors), MAF sensor (Like Dr.Q mentioned), etc.

Without a CEL or MIL, it's hard to diagnose.

 

Have you put any type of additive in the gas tank, i.e., octane booster?

 

guys u will never believe what it was. somehow the fuel shutoff switch triggered and cut the gas. i have no idea how but perhaps from slamming the door to hard. ne ways problem fixed thanks alot guys

 

i thought it was cuz you floored it too much..





just kidding bro, glad to hear it was nothing serious.

 

Make sure that no one backed into your car. I got rear-ended once in my 89 GT. Car ran like crap for a day. Fuel shut off thing was triggered when a truck full of illegals ran into me in a traffic jam. Hit hard enough that it popped the Hurst shifter plate out of the console. Tore bumper off of his S-10, and slided the radiator. Put a small nick in the tape stripe of my bumper cover where the screws from his front license plate hit it. I have no idea how it didn't cave the back of the car in.

 

I would've thought that, but I figured the engine wouldn't turn over at all, so I didn't suggest it. Who knew...

Glad you got it figured out though.

 

if someone did hit it the panels to access are one the floor beside brake pedle should be labled maybe on passenger side I forget but it is marked or if you got the engine wet you may have a fouled up sensor aboue a spark plug ?
