Your problem is with the fuel regulator, your getting fuel but irregular pressures(surging), I know this post is old so hopefully you've gotten it fixed by know. Most of the time when its bad it will rev up up then down. Also with the knock sensor its either pass or fail-to check it get a screwdriver and put on the block and tap it with a hammer if the motor retards a bit after each tap than its doing its job. It is designed to kill motor and make for minimum damage in case of engine malfunction(rarely ever bad)
my geusses is feul pressure reg (80% of the time) or fuel pump (10%) or idle air control (10%)
