That's very interesting. I'm experiencing the same problem on my R34 and i was thinking of changing the oxygen sensor, but i've noticed that's there's not much change in revs on idle. So i think installing some splitfire coilpacks might be a more likely sollution. So cheers for that info. Probs not a bad idea to get the sensor replaced anyways, i don't think it would have been changed in it's 100,000km life. Also thinking of installing a new computer, pod filter, intercooler and rest of the exhaust, rims, suspension and then getting it tuned. It's all stock, all it's had is a cat back exhaust installed.
Any advise on what i should do first or what order to install these?
Thanks!
