02 Cavalier Engine Issues

Hey all. Just want to get some insight from other Cavalier owners. I purchased a 2002 Cavalier LS 2.2 Manual back in early 2002.
After 8 months of owning the car, I started having issues.
First the engine will die for no reason while slowing down, or just pushing the clutch in. I have taken this car in a total of 15 times now for the same issue and no one seems to understand what is going on. I read threw this forum and really can't find anyone else having this problem.

Problems:
Engine Dies
Water leak in driver side floor board
Blower motor burnt up
Check engine light on most of the time
Air bag light comes on often
Gas mileage went down to 22 mpg (90% highway miles)
Loss of power while driving

Most of these issues have been adressed, yet the engine is still dieing. I now have a recording device installed in my car. When the car acts up I am to push this button and it will log what is going on. The 10 mile drive home was filled with alot of button pushing. All my gauges kept going off like I turned off the car, then would come back on.

I am at my whits end with this car. I am ready to "Drive my chevy to the levy...and push it in."
Any thoughts, advice on this issue. All will be greatly appreciated.

hrm. I have no idea sept maybe check your ground, to the body, clean it up scrape any paint away around it?? Just my un-educated guess.
