SOLVED-Trifecta after drivetrain work???

[ChevDog1]

At the beginning of this month (naturally just 4 days before our one large snowstorm of the year), my front driveshaft splines let go. Wife accidentally stabbed the throttle to the floor while holding the brake with it in gear while picking up our mail. I had to tow it the 1/2 mile up our hill from the mailbox, and stuck it in my shop until I had the time to sort it out.

On Friday, I received my new front driveshaft with the 1" longer splines, and installed it. Took the car for a quick test drive friday night after I finished, and it worked great! Problem solved!

Until last night... I took it to the gas station to fill it up so it would be ready for the school run this morning. When I restarted it, the ABS/DSC/brake lights were all illuminated. Driving away from the pump I noticed that the speedo wasn't working. Drove it home 2 miles with no speedo, and hooked up my Peake code reader. No codes, but I cycled it to clear codes anyway. Restarted car and everything was fine again. Tokk it for a 2 mile test drive with no problems.

This morning, its acting up again. Trifecta and no speedo all the way to work (35 miles). Tried spinning the steering lock to lock, and no change.

I had similar problems last fall, and had the ABS computer rebuilt in September to fix it. Could this be related to my driveshaft failure, the repair work I did replacing the driveshaft, or should I be looking for something else?

I really like this car when it's working, but I'm getting tired of working on it.
