Heres a couple of things to take into consideration:

1. Loose or damaged wire harness connections at distributor (5.0L) or Coil Packs (4.6L) Or the Alternator... Engine Controls, Computer and or connections to the computer... u probably shouldn't mess with all that, but if u really want too u can check the connections going to the computer... its behind the passenger side kickpanel (I.E. To the right of the Passengers Right foot... )

2. Intake manifold vacuum leaks. Make sure all mounting bolts/nuts are tight and all vacuum hoses connected to the manifold are attached properly and in good condition. Make sure there is nothing obstructing the air filter, also make sure nothing has gotten through the airfilter and possibly stopping up the MAF.

3. Insufficient fuel pressure. A variety of things could cause this... But seeing as how your not SEC certified or a master mechanic, lets just look over the small things... First check the Fuel pump switch or "inertia Switch" which is what kills the fuel pump if a collsion occurs (or maybe even if something hit a collision sensor, or maybe something could have even hit the pump or switch it self). This switch is in the trunk on the left side behind the carpet... it is a red button with a plug underneath it... Make sure the plug is connected securely, and then press the red button to reset the switch... Next if that doesn't solve the problem, check fuel filter, its fairly simple to replace and shouldn't cost more than 10 bucks or so... You are supposed to relieve the fuel pressure before changing the filter, but seeing as how the car wont run thats going to be hard to do considering u have to unplug the inertia switch and let the car run until it quits... but i guess u can't exactly do that... so just try and change it without relieving fuel pressure... Its infront of the gas tank underneath the car and its has connectors which common sense should tell u how to take it off... Anything else that could cause this insufficient fuel pressure isn't something that you should really be messing with so i'll skip to the next stuff....

4. Check the coil packs and the spark plug wires going to them... and make sure they are connected securely... Allso check to make sure the spark plug wires are connected securely to the spark plugs... Make sure they haven't gotten wet... Make sure you have the correct gapped spark plugs as well... Check the battery and alternator thoroughly... Check engine ground (probably not this, but i guess it could be).

5. Make sure your emissions system components aren't faulty... The only thing i can think of that would cause this is maybe bad O2 Sensors in the exhaust system... Anything other than that you don't wanna mess with...

6. Idle speed could be incorrect, Check the TPS (throttle position sensor) and replace if nessessary.

7. and last but not least, Something to do with the fuel injection could be malfunctioning... This you really really don't wanna mess with unless you know what your doing...


If none of this helps you might wanna get a professional to look at the car... Hope this helps... Good luck
