I am trying to adjust the timing on my 97 C34 with the s2 RB25DET in it.
I was having detonation so I checked the timing and it was on the crank mark furthest to the right when looking at it from the front. Came like this from japan, ran great, quik and smooth with a bit of det only on WOT runs. I loosened the CAS and set it to the 4th mark from the left(15 deg). Car hesitates under medium to heavy throttle, no det sounds and also hesitates when cold at parking lot speeds.
I am still unsure which tps plug to unplug, when I unplug the brown lower one, the car just dies. So I set it with the grey upper plug unplugged, but I hear thats the kickdown, so its probly made no difference.
So which plug do I use to get base idle?
