Need some help with my Skyline (1998 R34 GTT - Tiptronic - 4 Door - RB25DET Neo Motor - No Mods only Air Filter)
Picture 1: What is this box containing a circuit board in my drivers side foot-well?
Picture 2: What is this bolt hole for, does it require a bolt or is it not necessary (could it be creating an exhaust leak, or just housing bolt?)
Picture 3: Is it normal for this to get extremely hot? Could this contribute to rough idle/flat spots at low RPM
Picture 4: What is this wire supposed to connect too, as it is connected to Picture 5 which looks irregular
Picture 6: When unplugged rough idle "mostly" smooths out, however acceleration gets choppy with a massive power cut
Also having an idle problem,
- Rough Idle
- Flat spots and near stall at low RPM - mostly when accelerating from a complete stop or crawl
- When I sit at lights in drive with my foot on the brake, it jerks a little and sounds rough (Idle sits around 800)
- Seems to have majority of power under load but it's hard to tell I don't hammer it
- Exhaust sprays tiny specs of black liquid onto ground in tiny amounts on rare occasions
I will try upload a video of the exhaust so you can hear the idle.
I have replaced the air flow meter recently and changed the fuel filter
Advice would be greatly appreciated, I am still learning as I go
