You could have a sticky EGR valve, also the ign module could be going bad
SOURCE: RUNS GOOD STALLS AT DIFFERENT TIMES; ae. STALLS HOT OR COLD
when you removed the water pump, did you disturb the timing in anyway ???

Try checking the exhaust flow when someone else is pushing down on the gas petal.The farther the petal gos down,the more exhaust should be coming out. I replaced my catalitic convertor at 44000 miles, it was clogged. I had them install a high flow type.

I would believe the problem lies with the CRANK POSITION SENSOR. The computer relies on that sensor to advance the timing when the engine is cold, once the engine warms up, the computer will ****** the timing and then the timing will be set in relation to the THROTTLE POSITION SENSOR. The crank position sensor costs aroung 30 to 40 dollars. But to have it installed will cost probably around $300...maybe more. To install the CPS you will need to jack up the front of the car, remove the passenger side front tire, remove the plastic splash guards, remove the serpintine belt, remove the harmonic balancer with a special puller designed for that type of engine, then finally, remove two little bolts holding on the sensor and replace it with a new one...........it all sounds pretty easy and straight forward, but really there is not too much room for tool movement and your body will be in an awkward position most of the time. I can do this job in about an hour and a half only because I have done it so many times and know exactly which tools are best suited for each particular bolt and the whole process, I would say it is a 3 hour job if you are very mechanically inclined or a 5 hour job for the first timer.. ,

Good Evening, you might want to check those injectors, I can not remember for certain but that setup was sequential and when one or two have a problem it would take out the rest. Ohm out the injectors and see what you have there.

OK dose your engine light ever come on serivice engine soon mil light or is it on now If so then its a sensor problem with is not uncommon and easly repaired but you need to take the vehicle to your local auto parts store and have the engine code or codes read most places will do this at no charge and will be able to tell you witch sensor or sensors are the problem and most are placed so they can be easly removed and replaced If your not getting MIL light and you have done plugs and wires you should check the disturbtor cap and rotor they are just as important as plugs and wires and all should be replace at the same time during a regular tune up along with the PCV valve. If this dosn;t fix the problem then its afuel delivery issue witch means the vehicle is starving for gasthis could be the fuel filter is not leting enough fuel throw or the fuel pump is not pumping enough fuel. You said you have removed the filter once before so you know how to do it get a new one and before you put it in take a plastic bottle and the fuel line that comes from the pump and stick it in the bottle crank the engine for about 5 seconds the pump should fill the bottle about a thrid of the way up if you get less fuel then that the pump needs to be replaced and i mean a lot less if its close it is ok. BUT REMEMBER its a lot cheaper and easyer to fix the vehicle when you first see that there is a problem then to wieght because little problems have a way of turning into big costly ones good luck

Took off and srayed the egr valve.and inside theholes in the engine.Tried jiggling the keys to see if the car would cut off but it didn't. Don't know how else to check the ignition.
Does it seem you jerk and stall when coming to a complete stop when you have traveled faster than 4o mph? Ithat is the lock up in the torque not unlocking. Have you checked the fuel pump pressure when its ranning?
