Sounds like you have a bad fuel pressure regulator.Pull the vacuum hose off the regulator and if any fuel runs out of it then the regulator is bad .You will need to replace it.Also check for fuel in the map sensor which is another sign that the fuel regulator is bad.If they check out ok then replace the coolant temperture sensor.
here are some signs of a bad fuel pressure regulator: the vehicle runs rough, the engine will not start(usually in morning) MANY TIMES ENGINE STARTS BUT STALLS SHORTLY AFTER STARTING. a bad regulator can result in fouled spark plus, and fuel milage will decrease noticeably. the only cure is to replace regulator. what makes it fail usually it gets a tear in the diafram and it cant maintain fuel pressure. hope this helps toolman,
Those values and most everything else you need for DIY work are contained in the Haynes manual for your vehicle.
We have one with each of our vehicles and not only give you the info needed to do repairs yourself but also get an idea of how much work a specific repair should (or shouldn't) cost.

You can also buy these from auto parts stores for a few dollars less and sometimes on eBay for even less.
no timing belt on the particular vehicle. but yes probably something minor, check fuel pressure, fuel pressure regulator, MAF sensor and IAC motor. all these can cause intermitent stalls. The MAF is located somewhere between the air filter and the throttle body. it is a sensor that sometimes gets dirty with air particles and will affect fuel managment. the IAC motor is on the throttle body and if gets stuck with carbon will not be able to control idle. the fuel pressure regulator is on the fuel rail and if the vacuum line is filled with gas then the diaphram is bad. and the fuel pressure should be 35 to 50 PSI running.
