Default Stumped on Electrical APP and TCS problem

I have a 99 coupe H/C/I and all the bolt ons. I have been doing alot of forum searching for a solution. Long story short I have TCS codes 1243 and 1278 constantly ( I am thinking about manually activating the ABS pump as a possible fix). And randomly i get "reduced engine power" and PCM codes 1125 and 1281 become current.
So Far:
- I checked and greased most of the grounds and they looked good.
-cleaned and greased the connectors on the throttle body which did have a alot of corrosion in them. Hoped it was the cause but the problem is still there
-checked the Accelerator Pedal Position (APP) connector and looks clean but slots D and E look like they wouldn't have a good connection with the corresponding pins, like they have been smashed down or something.

Not sure how well you can see it in the picture.




Could this be my problem? Is there a way to fix the connector?
I would hate to have to cut wires and solder a new pigtail inplace. but they are that cheap. http://www.eficonnection.com/eficonn...omponents.aspx

ANy ideas would be appreciated thanks

You can tighten those 2 pins up a little with the right dental pick. Also can be removed from the backside, instructions in the service manual.

I tried to bend it back out with a safety pin but couldn't get the right angle. I don't have a service manual but that sounds like the ideal path. If some one could post the instruction i'd appreciate it.

Or sometimes you can use a small paper clip to come in from the backside to release the pin. Paper clips of different sizes can come in handy as they are stiff enough. I've done this many times. Once the pin is pulled free, I use one of my smallest jeweler's screwdriver's to re-form and/or straighten the contact and pull the latch pin back up before re-inserting in the connector.
It's a bit tedious and requires patience, but it CAN be done.
