Hey Guys

Been trolling the forums for a while and seems like this happens a bit..

I own a r33 97 s2 skyline, with an rb25det engine in it..

the car has been miss firing on a cylinder on and off for a while now.. some times it misses and comes back good, some times it doesn't and i need to turn the car off for like a minute and then it will restart fine.

I have replaced the plugs in it. first up it had standard NGK Plugs in it with a .8m gapping and replaced them with NGK PLatium plugs at 1.1m and this seemed to fix to until about a week down the track the fault reoccurred. Thinking that the gaping was big i bought some more standard plugs with the .8m gaping and it still plays up. The NGK plugs i pulled out were orange as well which i found to be odd. This only seems to happen once its been running for a while. But it is becoming more frequent.

Could anyone tell me if my car has OBD2 or 1 ?

I have placed a bottle of injector cleaner into the car as well which has well and truely gone through the system by now.!

Can someone please point me in the right direction. !

Hey guys just been playing around with it to test the coil packs.

When it plays up remove the a plug on a coil one by one.. a change in engine nose will indicate a good coil and no change will indicate a bad one..

I have no bad ones to say.. but just a bad connection.

On a coilpack i noticed if i stuck the plug in a certain positon the fault would clear, and by moving it back it would reappear.

So i think i have this thing sorted now. I was already to go out and buy some new coil packs .. looks like i dont need it now YAY !

Cheers guys

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
