Car ran fine, now dies right after being started
I took my car (2001 GLS) to wal-mart today after a doctors appointment, it drove and ran 100% fine the entire day. After doing my grociery shopping and loading the car up, i started it and it felt like the motor wasn't even running. Then it died.
Its 19* here and after unplugging the MAF to see if it would run at idle, my hands were numb and it still didn't run. So i figured i would post on here tonight and see if anybody has any ideas what it would be before i go back tomorrow and troubleshoot it myself (hopefully its not cold LOL)
Thanks for any help

haha, i've been using this name since long before the movie was made, and no the security light wasn't on (I checked that first) my probe used to do the same thing so i had to disable and remove the factory alarm.

could be a clogged fuel filter. How are the lights and such? Did you try jumping the car just in case? Cold temps could have affected your battery's performance...

well the car turns over and starts fine, its just that once its started it feels like there is no power, and if i keep tapping the gas it will barely hold an idle.
as soon as i stop playing with the throttle it dies, Or if i start it without throttle it dies immediately after its started.
Also, if anybody knows what it is, you don't need to sugar coat it as far as technical terms go. i can handle it I just wanted to post on here and see if anybody had anything specific to look for, i will be troubleshooting it myself tomorrow but anything that can make this process faster is better

check your air filter, sounds to me kinda like it's got a lack of air to the engine, and if you're not way into the throttle it can't get enough to stay running.

Its more than likely your Idle Air Control Valve. Mine in this cold weather is doing some stupid stuff too. Try unplugging it, then plugging it back in and do that relearn procedure thing. Or if its got alot of mileage on it then you may want to replace it.

All good suggestions, but unplugging the MAF was a waste of time (what's the thought process there?). I'm thinking to check for vacuum leaks.
It's not the battery, or the car wouldn't crank and start. If you want to verify that then get one of these while you are at Walmart and plug it in:
Equus 3721 Battery and Charging System Monitor
But it's still not the battery. My 1995 Escort is at 5.5 years on a 5 year battery, and even then I can see it charging the battery at the alternators maximum allowed voltage all the way to work (13 miles) on the highway, but it does not affect how the car starts or runs.
I can't think of anything that might be cold weather related unless it's a sticky IAC.
How many miles are on the car?

Not only that, if the car is run with MAF unplugged for long (at that point you likely would have to keep tapping the gas pedal to keep it running), it may be harder to restart it anyway after you reconnect it -- the PCM's fuel trims could be thrown off.
Could be a few things, TPS, fuel pressure drop, IAC....

to be clearer, i didn't intend on driving the car without the MAF plugged in. it would just die as soon as it saw throttle. i did the same thing in my brother's explorer and it would idle without the MAF plugged in.
I'll do the IAC thing tomorrow, the car has 140,xxx on it, but i've taken good care of the car since i got it at 100,000 miles

The problem is with these cars, if the MAF is unplugged, or fails, the PCM reverts to SD mode, and uses the VE (Volumetric Efficiency) table in the computer to calibrate the fueling. That VE table is rarely calibrated closely enough from the factory to keep the car running smoothly, and also affects the tranny's shifting.

Im going to also go with Fuel filter and or bad gas. But your car will not run with the MAF unplugged and if it does it will run like a turd

Gremlins is the only suitable answers here. Your car is obviously upset that you use it for groceries. That's what honduh's are for.

I tried driving my 1995 Ford Escort with the MAF unplugged. I only drove it for a mile before I pulled over and plugged it back in. The only thing that happened with it unplugged is that I got a dash light. I was not going fast or anything either.
