95 E320 - Test results help please.

I have replaced the wiring harness on my 1995 E320 Cabriolet. Also I replaced the wiring on the Electronic Acelerator. I am having an issue(s) that I am hoping someone can help me with.

When I turn the key to on the EA makes a loud click, also I can feel the throttle pedal move right before the click of the EA.

I am able to start the car by pressing the pedal just as it fires. I also have to use the pedal to keep it running.
I am having to push the pedal beyond halfway down to get the throttle to respond.
Once it warms up it wants to idle around 4-500 RPM.

The car can then be driven although the shift points are high, 5500 RPM from 2nd to 3rd. I usually let off the pedal and it will shift. Downshifting does not seem to be a problem.

The Check Engine light comes on a day or so after clearing codes. The ASR light is always on.

I have pulled the following codes,

Pin 3 =
6 - Idle speed control faulty
Pin 8 =
8 - Idle speed control (ISC) system at upper or lower control stop or
CC or EA indicates "limp home" mode.
Pin 14 =
3 - Right EA/CC/ISC actuator (left cylinder bank)(M16/1)
11 - Closed throttle recognition signal to engine control
module (HFM-SFI).
Fuel safety shut-off to engine control module (HFM-SFI)
14 - Closed throttle position contact switch

I cleared the codes but they came back the next day. Each time I clear them the same ones show up daily.

I then decided to do testing using the AllData EA Test Steps from the Trouble Code Diagnostic Charts.

I copied and edited the steps to show my results and notes. These are included as 4 attachments to this request. I apologize for the attachments being a bit blurry. Resizing issues..........

Tests used were 2-10 and 19. The results of test 5-9 were within the Nomian Values listed on the charts.
Number 19 was not good. The results seem almost backwards!
Tests 2-4 were within range of the nominal values but are curious in that if I switched the results they would be more realistic(closer) to what I would expect to see. I am probably misinterpreting the data!
Test 10 was 0v although at first it was 14v then quickly went to 9v and finally to 0v. I am thinking this is fallout from the other results.

I almost seems like I have the Closed Throttle and Wide Open Throttle signals reversed. I did replace the Closed Throttle Sensor in the gas pedal assembly.

Any help or insight would be appreciated. Hopefully I have not provided to messy of a description of my troubles!!!

Take Care
Tom
