List of items changed in chasing this ghost so far: Fuel Pump assembly; Fuel filter; plugs; plug wires, catalyc converter & exhaust; both oxygen sensors; temperature sensor; EGR valve; throttle positon sensor MAP sensor; battery; air filter. What do you suggest may be the real issue with this vehicle? Thank you.
Change the coolant temp sensor,and possibly the EGR position sensor.

Could be that your coil pack has gone bad. This is not a cheap piece though, so you will want to be sure.
Does it run fine when up off of idle, or does it also seem to be missing as you drive down the road.

It is possible that you could have a bad spark plug wire, or a bad coil pack. Also it could be your TPS Throttle positioning sensor. Check spark on each wire to verify that you are infact getting spark the whole way across. If you are then I would suggest changing the TPS as it is inexpensive, if that does not help it could be your MAF, ( Mass Aif Flow Sensor) Hope that helps

OK. I ran a test on the EGR valve for 3 days disconnecting the vacuum line and pluggin it. The car ran fine with no problem. I replaced the EGR valve, connected the vacuum line and the problem is back. Actually the car stalled in the driveway.I left eh electrical solenoid connected at all time, but the EGR does not actualte without vacuum. The solenoid is actualted by the PCM, so is it the PCM, or something telling the PCM to actuate the EGR valve?
