Check your plugs, this is most likely your problem if it's cutting out at low rpm.

BTW, a surge is when your RPM's raise without touching throttle.

How where you able to turn the cam sensor 180?

Since you've been playing w/ your cam sensor you might have advanced the ignition timing to far and are getting lots of rod knock, hense your motor cutting out. Try putting higher octane fuel in, my cam sensor is advanced 5 degrees and have no choice but to use 91+ octane gas to avoid knock.

new plugs

if you put in new plugs, replace the plug wires too, and maybe a new distributer cap also.
