Hey guys,

hopefully some of you might be able to shed some light on a miss fire issure I'm having with my cefiro, basically the car won't rev up it just coughs and splutters once you apply a bit of load to the engine and it sounds like it backfires in to the inlet manifold if you try and rev it up too much and it seems to be related to number 1 cylinder

I have done the following to the car to try and track down the issue and some other probs i've noticed as i've fiddled around

replaced plugs with new BCPR6S 0.8mm gap

tried disconnecting the coils and tracked it down to number one cylinder not firing

swapped around coil packs with no change in number one

tried another ignitor module, no change in issue

tried checking all wiring plugs are all connected properly (with this i noticed if i wiggled the CAS plug to much the car would stall, similar with

and have had a look over the cooler piping, but this wouldn't lead to the problem being only located in number 1

If you have any ideas that would be appreciated as I'm totally confused and don't have many more ideas, apart from wiring being damaged but i haven't done anything to warrent this

cheers

Nick

check your afm, when the afm is in limp mode it wont rev past 2k

open up the afm, check for solder damage, also check the plug is in a healthy order

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
