Not sure if this fix is the same as the gas pedal post but here goes.  Sometimes when starting the car it will die without the gas pedal being held in just a bit.  If you take your foot off the pedal when it's acting up it will die.  However after about 5 to 10 seconds of holding the pedal down just a bit it runs fine and idols great.  Sometimes it's in the morning after sitting all night and sometimes it's after driving and sitting for 5 minutes.  Sometimes it goes days without acting up.  I did discontent the battery for an hour and it ran great for 4 or 5 days after that.  Any thoughts?  I did pull one of the front plugs but they look ok.  The car only has 100,000 miles but I've only owned it for 15,000 miles so I can't tell you if any work has been done except for the notorious gasket.

I assume you have a 3.1 liter engine?

If you look in between the throttle body and the intake plenum near where the throttle cable is attached you should see the fuel pressure regulator. It will have a small vacuum hose coming out of the top of it and a fuel line coming out of the bottom. Remove the vacuum line and start the engine. If fuel comes out of the the regulator where the vacuum line would have been attached you found the problem..... Or at least "a" problem. Replace it and you should be good to go.

Did Jeremy's solution fix this problem? I was wonder if it could possibly be a dirty MAF sensor. Are you throwing any codes?
