Thank you Arthur Dalton and Phantom Lord. I was at work and without access so had my family post now back at work. Will check this post later thanks so much to any that can help. This is frustrating.

E320 1994 W124 body frame.



If the Fuel pressure regulator is on the front of the engine just off the right side of the center of the motor then yes I checked it and it is not shooting any petro out of it.



I plan to visit Radio Shack tonight after work and see what I can do about putting together your code reader.





Note: no matter what speed I drive I can still feel the surges. They are tiny at higher speeds. I am going through twice as much gas, I was getting 27 MPG now it has to be half of that. Also, when I come to a stoplight the car will sputter while surging. One time when I slowed down the car started coasting on me. If I turn the car off then restart I loose the sputtering, but still have the surge. Again the surge revs at Idle between 500 and 1,200 RPM. Right now I have no indicator lights on and I know all bulbs are working. I feel that it might be a vacuum leak because I believe I hear something behind the black pipes on the right side of the motor. I believe that would be the Manifold.

Thanks again for any insight.
