What should an ngk tr55 spark plug be gapped at? I gapped them at 45 thousandths. Is that too much? The miss I have is only in cylinders 5 and 7 when the moter is on closed loop. I dont know what to do. It gors away when that car gets hot.

 

The stock gap is .05, with you mods I don't see any reason to run any other gap than that.
