any engine will knock, whether it is PFC or stock ECU........ i would worry too much about it, a friend's R34 did that as well and he never mention anything about being worried about it, but if in doubt get it checked out by your mechanic/dyno dude :rolleyes:

lol no, only a PFC will trigger the CEL for engine knock, the stock ECU will not display the CEL if there is any knock detected....would be great if it did :rolleyes:

If it was a brief flash 9/10 it's the O2 sensor, if it goes on an remains on, most likely coil packs..run the diagnostic to be sure.

Paper clips at the ready!!!!!

As the document says, turns the ignition to "on" short the two terminals indicated on the consult plug (clipped covertly on the underside of the dash near where your right knee lives), count the flashes, look up the code

diagnostic.doc

Thanks Dan lol

Hi all just to clarify... This happened to me today. The engine light turned on and stayed on after 10 minutes of driving. I didn't feel any change in the engine etc. car felt as usual no hesitation, shakes or missfires.

I pulled over waited a few seconds and restarted - engine light was off and never came back on.

I guess i'll have to drive the car more and observe if the issue comes back.

My car is an r34 non-turbo auto btw.

What is the consensus on this? Bung sensor or coilpacks about to give out or ecu glitch (if that even happens)???

Definately coil packs, fitted Splitfires and iridium plugs to mine today. My engine light had been on for a week and a half but like yours had not yet shown any signs of hesitation or missfiring yet. Just ran the engine, no engine light on and appears to be running much smoother and cleaner than before.

Splitfire coilpacks, part# SF-DIS-008, Brought them from CRD in NSW for $510 delivered, awsome service as they arrived a day and a half after payment.

NGK Iridium spark plugs BKR5EIX-11 $90

Also have NA R34 Good luck, Nath.

this happened to me, engine light came on and it dropped a cylinder, car would shake quite a bit, so i unplugged the coilpack plug, replug back in and the shaking went away.

pin pointed it down to the one SOB coilpack so i replaced that.

hopefully its fixed now as i only did it 2 days ago but so far so good, the light would come on intermittently, sometimes it would last a week without issues or maybe a day... but then in future if more packs let go, its time for splitfires.

My engine light came and and I got a service they hooked up the Nissan computer but they couldn't find the problem. I rang Power Road car sales where i bought my R34 Gt from and they identified the problem by just me explaining it over the phone.

I just got a new coil pack installed by them today, costing 240, (130 for the coil pack form Nissan) They also claim to have a machine that tells them which coil pack is playing up.The car runs smooth now, but my engine light is still on. I was told that the computer needs resetting, but I would have thought that the light would switch its self off once the problem is solved.

Does any one know how to reset computer or do i need to take the car to a specialist?

^ dc the battery, step on brake a few times to compeltely drain the power.. wait a few mins, connect battery back up & thats it.

but after u change the coilpack, u turn it off and then turn it back on and the engine light should go away.

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
