Hi, so I'm trying to diagnose two problems. The first deals with intermittent stalling; the second, low boost.

Anyway, I took out my KLR for the first time and found that it was from an '88 Turbo (not sure if S or not) -- my car is an '86.



So I took it apart and I found what looks like the copper separating from the board:








Do I need a new KLR? Could this be what is contributing to my low boost? And BTW, I have literally done everything I could both think of and find here on the List and nothing's worked. I'm constantly at 1.25 bar, and have been so since I bought the car back in Feb.



One more question: What's this plug? It's in the DME wiring harness.





Thanks guys!

I would poke around with a dental pick in an area of the board with no traces. Like around a mounting boss that is peeling.

That could just be conformal coating (clear protective coating boards can have) or the solder mask (green stuff) lifting. Which would not cause problems unless something conductive made its way onto the board.

If the copper is indeed lifting, the board either needs surgery of some sort. Or replacement.
