Check Engine Light

I need help diagnising the cause behind the check engine light on my 1991 9000 turbo. I read the posts with instructions for reading the codes, but have not had much luck. U have a switched ground, but it doesn't seem to interrupt the ground.
Anyway, I have checked for vacuum leaks and found none so far. I swapped a DI cassette, replaced the air cleaner and cleaned the AMM with electronic cleaner. I cleaned its connections as well. The car seems to run okay, but I can tell that it is down on power and seem to be running ruch by the looks of the tailpipe.
Anyway, any suggestions?
Dan
