one more thing... when the engine light is on, car vibrating slightly on idle idle still stays fine (0.8) after restarting engine light is gone and vibration gone too any ideas?

sounds like the same....i'll try to replug them thanks

ok, I've run ECU diag and got code 21. (two long flashes, one short) 21 Ignition circuit What should I do now? How to check/repair. please help as i'm new with skylines

I though there is oil light is oil level is low. But it's not low. Oil pressure is in the middle when the car is hot or close to right side when cold or accelerating really high. I don't know how to check oil temp... What else can I check? thanks

hi all I got engine alert (that yellow one on the dashboard) few days ago. I stopped the engine and waited for about 2 mins and started it again. No more alert. I've been driving after that for about 2 days and no problems. what could that be? what r the first things to check ? I think to run ECU diagnostic first, right? If so, is this http://www.powerlink.co.nz/~graeme/faq/14.html the correct manual? My skyline is R34 GTS-four. thanks!
