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!

Engine light will come on if oil is low... might want to check oil pressure, temps, etc.

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

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?

One cylinder is not firing, so you will get a slight vibe.

The computer will compensate for drop in idle and it will try to idle like nothings wrong.

Try disconnecting plug packs one by one and find out which cylinder it is.(If that doesn't help the other thing it could be is your ignition module).

Less likely: Have you checked your spark plugs.

      Out of curiosity, how do you cover up the inspection hole? Surely it doesn't sit open like that, right? With grime and dirt coming in and oil going out?

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything
