Default Could it be..........the PCM?!

many of us have experienced surging problems at low rpms, especially on the uphill with the TC locked. marksssei showed us that this may not be the fault of the TC, but rather a dirty MAF giving the computer the wrong signals. in his case, cleaning the MAF has resulted in a cure for over a month. but what if the problem goes all the way to the PCM? i ask this because our '95 Olds Eighty-Eight has had (and this is no joke) at least 4 faulty PCMs go through it in the last 2-3 years. i may be way off base here, as i don't even know if bonnies and 88'* have the same PCM. but its just an idea. has anyone with an aftermarket PCM had these problems? let me know what you guys think.

I know my parents had to replace the PCM, or more commonly known for the car, and ECM, in their 1992 Olds 98 Regency Elite. I also had to replace the ECM in my 1992. Can't remember why in either case (my 1992 was really needed, but I was having a slight problem and it helped to swap in the ECM from the 1992 SSE I had at the time -which reminds me -it'* still there if Jason needs or wants it -probably won't work in his application).
