Getting boost in neutral

Recommended Posts

My car won't rev above 3000rpm and is creating boost in neutral above around 1500rpm. It's running realy rich at the moment and my only mod is a front mount intercooler and the pipes aren't leaking.

I was wondering if it could be the O2 sensor because in fluctuates between .5 - .8 volts at idle even thou it's running rich.

How can I test the airflow meter.

Any help would be much appreciated.

FOUND THE PROBLEM (I hope)

After I changed the cam belt I thought I wouldn't put the dust cover back on to see if the belt stayed tight. At the time I didn't know there were spacers in the cover to space out the crank angle sensor. I drove the car around the block and is stoped. Towed it home. Have been driving it around for about a week now and the above problems occured in the message above. Just checked the timing and it was really retarded(would only just idle). Pulled apart the crank angle sensor and the input shaft was snapped. An expensive mistake to make.

*Please note to anybody thinking of removing the cam belt cover you need to put spacers between the sensor and the cam gear if you leave the cover off.

    • Hi all,   I have been a member here for years and am back to owning an R35.  It's my car and thought members of the community might enjoy sharing my journey.  I am definitely here to join the conversation.  If sharing this content isn't appropriate or it belongs somewhere else, I am happy to have it deleted or moved...
    • Data looks rock solid? I'm assuming you jabbed the throttle twice OR once? the TPS voltage moves up and down twice, however you've mentioned you did it once.
    • Having not watched the videos, I'm unsure, but this may be better suited to the importing thread?
    • Update on this situation: (Forgot to put in my previous post that I bought another brand new pressure gauge and fuel shows the same 50psi) I've deleted all the aftermarket immobilizers and turbo timer shyt and placed all factory wiring back to normal. The problem is still the same and nothing changed, but atleast it's a bit more tidier under the steering wheel. I've also siphoned out all the old fuel and then poured new batch of BP98 fuel (about 15L) into the tank. Nothing changed. Still the same idle. I also changed out the MAP vac line with a new one and, still the same.  So 2 days ago, I thought fk it. I'll just change out the fuel rail and injectors with another set that I know worked well in my brother's R34 a while back. That other fuel rail has the exact same Xspurt 640cc as what I have right now. So I changed it out to that other fuel rail and injectors (new O-rings) and injector harness. Put everything back together, started the engine, 464906286_1624569924763105_5179888796065901094_n.mp4   and yeah... still the same 50psi and idle problem. 🫠 I can also hear each of injector's solenoids running when I put a screw driver to it and have the other end to my ear. I might get a noid light just to confirm pulsasion but yeah, very strange that both fuel rails and injectors put out 50psi.  31-10-2024.csv I've attached it here. I started recording, then started the engine and let it idle with no throttle, then at the end I applied a little throttle and then stopped recording.    So, now idk. I'm going to see if swapping out the brand new R35 coils to my old splits fires will change anything. 🤷‍♂️
    • Hey mate, nice work on the car. Just a quick note, people generally don't like it when you use the forums to dump and run to advertise your YouTube content. If you're gonna stick around and join in the conversation then great, but if not this might not be the best place for you.
