Bank 1 EFI Problem

Okay here is what I found......
I pulled the computer out and all the way apart and inspected it.
The caps were good and all the solder joints looked perfect. There was some corrosion on the part of the board (looks like a test port where the plastic cover is on the case) that was not covered in the clear rubber stuff that they spray on the board to protect it.
I cleaned that off with brake cleaner and covered the area with dielectric grease. She fires up and purrs like a lion now. Wonder if the corrosion was making a path for electricity to go to another terminal.
Hope this fixes it!!!!!
