.SUBCKT SPARK_GAP2 1 2 PARAMS: V_GLOW=1500 V_ARC=150 I_SUS=.002
V_BREAKDN=12000 I_ARC=.2

* SINCE THE STRIKING IS VERY FAST, IT IS STRONGLY ADVISED
* TO SET TRTOL TO 1 VIA: .OPTIONS TRTOL=1 and ITL4=1000. THIS WILL
FORCE
* PSpice TO BE MORE VIGILANT IN THE VICINITY OF TRANSITIONS

The issue with the syntax is the line that starts \")}\". This is a continuation line, and should be preceded by \"+\". Alternatively if you remove the line break and terminate the previous line \"> {I_ARC}, 12,0,)}\" the spice model will run. Good luck.
