That jerk your felt is most likely software related if you still run the older MSD80 software. Very common. It happens when engine is cold and can not be reproduced in DS mode. I get the jerk often because I never bothered to update the software.

My recommendation is just to check the battery. I jumped my car once because battery died on me and when I restarted I had transmission light on and it locked up in 3rd gear. If battery voltage is low it can't supply all the auxiliary components and odd things start happening.
