The car will start "jugging along" at intermitient times. Sometimes it is after the car has only been driven for a short time and sometimes after it has been driven for a while. It may occur ideling in traffic or on the interstate. There is a sulphur odor when this occurs. Sometimes the check engine light will come on. Sometimes I will turn the engine off with this occuring, turn it back on a litte while later and it is gone, sometimes not. The check engine light may or may not still be on. I have had the car to the mechanic and the computer says it is various sensors. I have them replaced and it stops for a while and then comes back. Of course, the car will not duplicate its antics when I take it to the mechanic. I think the car is possessed. Any suggestions?

The exact codes from the computer will help. But any sensor or even the injectors or fuel pump can cuase this, has the fuel pressure been checked?

Have the car hooked up to a scanner check every passive and active sensor/solenoid to see if they are in range. Then do a drive test hooked to scanner.
The results should indicate a course of action.
The end result may point to the PCM being demonicaly possessed.
Good luck
