P0108 Code

My car turns very rough and then turns off as soon as I let go of the key... won't hold an idle...

Checked the MAP sensor and when I tried to pull it from the hose the tube was very brittle and broke...

I put in a new MAP Sensor and checked for bad hoses... Still can't get the car to start! :(

Any help will be much appreciated! :)

We can assume you have good fuel pressure? Google that code, plenty of info. If it dies soon as you release the key?, suspect wiring or in switch.
