engine diagnostic codes please help

I have just recently had my car checked and it came up with three codes which had to do with misfire of the ignition. and i was wondering could anyone out there pin point my problem or elaborate a little more on this the codes that came up were p1323, p1350,p1375. and my car is a 96' aurora with the v-8 northstar engine. any suggestions would be gladly appreciated.

Looks like a 24x crank sensor issue, check the codes in this link. http://service.gm.com/gmspo/mode6/pdf/1996/96c40C_G__yE.pdf

Thanks,Your the Man! I had went to place a new crank sensor on and noticed there was actually two sensors next to each other, and at that time i had taken one sensoer plug harness off, and looked a secound time and noticed the other plug was also off, then i plugged it in and it had solved my problems which has been going on for up to two years now.( all i have to say do not trust taking your cars to a shop to have it worked on, i think this was intentionally done to bring the car back for service. In the meantime it had blowen out all 3 of my oxygen sensors which i have to replace. all i can say this is a wonderful site and very helpful for the do it yourselfers.

Nice job pinning this down, thanks for the post back.
