Ignition system questions?

Hello everyone,
I have a 92 Bonneville SE with a 3800, i had a problem with a code 41 " Cam sensor circuit " the car would also stall and sometimes not start at all, just turn over and it had no spark. After about 5-6 times of no spark condition it would finally fire. The car stalled while driving also, i replaced the crank sensor & cam sensor they were cheap enough and the car has 160k. Stalling while driving had stopped. No start condition also had stopped. Now i still after clearing the codes get the SES light on once in a while " code 41 again " I went to the junk yard and grabbed a PCM switched the prom and reset the computer again after driving it for a day. Code 41 came back, anyone thinking ICM? Any help will be greatly appreciated. The car runs great by the way, just that damn SES light.

Thanks,

The ICM is a good guess but I would also check the wiring to the cam sensor. You may have a loose connector or a wire that is rubbing and making contact causing it to throw the code.
