Hi guys,
I noticed you mentioned that the cam belt does cause rough idle and the occasional pop?
I just got my skyline from japan, it's low on Ks, about 45+ thousand (I'd bet it's knocked back), other then that it's clean. However, idle is alittle rough when it drops to about 500 or 400. I can hear the sound of the engine rising and falling. It gets alittle worse when I turn on the lights.
Any ideas? I'll have the plugs and fan belt changed soon, I hope it'll help.
