Sputtering 3000RPM - V36 Skyline VQ35HR - Help

Hey people.

I'm just wondering if anyone has any idea whatsoever what the issue may be with my V36.

It recently started sputtering around 3200RPM as you can see in the video (Please ignore my dodgy display), nothing has been changed recently and I have tried resetting the ECU/throttle position/idle air/etc.

I've checked for exhaust leaks and can't seem to see anything, the ecu is throwing a throttle position sensor code however advice from the interwebs mentioned to just reset the throttle position and nothing more.  Happens in Auto and tiptronic regardless of gear, the only time it doesn't occur is when my foot is to the floor however that isn't feasible :P.

Cheers in advance!

Dead/dying coil(s).  Dirty AFM.  Dying fuel pump.  These are the usual suspects.

Cheers for that, cleaned up the AFM however that didn't resolve it.

I'll try have a look at the coils/fuelpump soon however I would've thought this would happen all over the rev range if it was them?

Decided to tighten all the bolts up and clean the throttle bodies then reset the tps/etc.

 

Codes afterwards are:

2133

0228

0133

Seems to be something to do with either the TPS or Accelerator pedal however I cleared the codes then went for a driv3 and intermittently the CEL would flash once for a second or half a second then go off randomly, car wss driving fine during this time.

Any ideas?

Its the weirdest case now because there are zero codes showing, and no CEL comes on anymore however still something weird at that 3200 range.

Took apart the accelerator pedal but all looks pretty fine there aside from someone having opened it in the past and put an extra spring in with a piece of foam.  MAF and Coils diagnose fine ?

New weird issue...  Slip/ VDC off / 4WAS light recently came on after I started driving today....interwebs says brake fluid but that definitely can't be the case.

In saying that I did recently pull the calipers off and paint them, I'm wondering if a sensor in the hub got damaged from impact wrench...?

Have you recently installed a new BOV or POD Filter? If so, try going back to stock and then seeing if this has stopped it. Might be a malfunctioning product or your car needs to be retuned after adding new parts.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
