Looks better... Now 2 codes so far...
You may need to trouble shoot the Crank sensor.... The car will run if it loses its 18x pulse... As long as it has a 3x'* pulse...
Man that car is cranky...
When the SES light comes on does the car act any different?

Ussually when the light comes on it runs like crap. Today, it seemes fine except for a possible slight skip at highway speeds. Ran like a champ around town and at lights where it ussuall stalls. What am I looking for with the crank sensor?

With the PCM reporting a loss of the 18x'* pulse, the PCM will not be able to run in SFI Mode... It won't be able to get the fueling right when it sees this loss...
Someone should be able to tell you how to troubleshoot the sensor... But it would have to have that failure at the time your troubleshooting it...
It looks like the PCM may have been one of your issues from what you described..
The Crank sensor may be the next on the list

Well, I put about 90 miles on it today and another 50 after clearing the codes. So far, so good. I'll look into the crank sensor if I have an issue again, but I wanted to thank everyone here; you guys saved me alot of time, money and aggrevation. Thank you very much, I really appreccieate it.

One other thing, is there a good website to pick up the Electrical Service Manual?
Thanks in advance.

As far as the Electrica Service Manual, if you can't find one on ebay, go straight to the source: www.helminc.com . I don't know if you can buy the Elec manual separately, but you can buy it along with the complete service manual. The p/n is 94BUICKCH. It'* $105 (ouch), but is all you'll ever need.

Sometimes, Helm runs specials. If you can afford to wait, and keep an eye out for them, it can be worth your while. I got my new '95 set of FSMs from Helm for $45!
