Hi, I'm fairly new to posting, have searched the forums for answers but get nothing specific so sorry if you have heard it all before:-

Got a stock R33 (Auto) Series1, have a 3" Exhaust from cat back, blow off valve and air pod. When I am at low revs around the street I accelerate, then let my foot off.....it then drops revs to about 500 and almost stalls, or it has even stalled once or twice which is not good. Any ideas? I tried putting a stronger earth for the fuel pump but no change.

Also driving at about 60km, the car sort or drops down then picks up then drops down, kinda like changing gears, but my foot isn't on the accelerator very much.

Hmmmm............

sounds like you might have a head gasket or dropped cylinder problem....get it pressure tested at a mechanics (in your capital city) and see what they say

another thing it could be is the air/fuel mix. If the Air Control Filter (which is electronically controlled) is acting up and not closing properly you will be getting air intake when your not supposed to and causing a drop in revs.....

also check the Oxygen sensor

I have this problem too.

You have to do 2 things to reduce the effects of this problem.

1) Clean the throttle body

2) Raise the idle RPM

Note that it doesn't get rid of it entirely. However the car becomes very much less prone for a stall after acceleration.

I have also heard replacing the AFM will also help.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
