hey 33SOM,

i have been having the same problem with my r33 for the last few weeks.

Sometimes it will idle normal then other days its around 1500 to 2000rpm.

i have found with him that if its idle is normal and i give it a good bang, it will then go up to the high idle, but if i drive normal shift at like 2500rpm it seems to be fine.

when i get off my ass i will try everything u have done

Looks like a problem that occurs when ya have a power fc installed

haha

i had mine installed in october

november, i started noticing the idle repetitively going from 500 to 1500

not the best look when you have stopped at the intersection.

i'm am in the midths of looking into it .

my AFM is not the cleanest one i have seen, and going to clean my panel filter aswell .

i will clean the AAC valve aswell, and replacing my fuel pump with a bosch 040 which i have recently purchased. ( Nothing to do with the idle but anyway).

I will also check the spring on the throttle butterfly, the "cold idle valve thingo" and the TPS, whateva that is.

After i have mucked around with these possible solutions, and i know then that its not them and they are clean. i'll take it to, "hopefully" a person that knows what it might be, and fix it

One good point from this, is my car seems to run quite smoothly when driven, like an idiot (not on the streets of course) or like a granny.

Just the idle is the problem

I also have the problem of turning my car on.... sometimes

it decides to just click and not start, eventually it will start

im guessing my starter motor is rooted, or fuel pump.

(Replacing fuel pump soon)

Any advice as with the other two fellow ppl with the same fortunate problem.

Would be much appreciated and less stress on me

Thanks

You have an alarm? A dodgy immobiliser caused that once for me.

i have a mongoose alarm

it did work properly.. once

at the moment, when i press the button to lock the door

it doesnt lock, but does arm the car if you do open it, and the alarm will go off.

i actually have to press the button to arm then use the key to lock the door. Its very fun, but i do atleast know the doors locked.

I have a new motor to put it, will be fixed soon

i will also check the immobiliser wiring and make sure it works properly

THanks for that.

    • 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 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
