Hey my car misfires alot, when i pull the engine to the max it seriously misfires, and when I try overtaking cars in the highway it doesn't stop misfiring, sometimes the boost starts pumping up and the rpm starts dropping no matter what I do till the car slows down, I have stock headers, turbo, trubo dump pipe, down pipe and suddenly a 3 inch exhaust pipe.

I changed my fuel pump, my plugs, my airflow meter which helped for a coupe of days but then it started again.

Help!!! when I start the a/c my engine starts stalling, and at idle my engine starts to dying out especially with a/c.

I broke my hoses that carry oil from above the engine where do i get the newer one?

Waiting for reply,

Falah

if ur car is boosted, u should to regap the plugs to around .8 due to the change in turbulence in the combustion chamber. if it still misfires you have a bad coil

if car is not boosted, change ur plugs, if it still misfires u have a bad coil

if still mises you could have bad wiring to coil or bad wiring, or bad fuel mixtures, VERY VERY RARE

Faulty air flow meter can seem like a misfire if not experienced

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
