Heavy Vibrations! Help Me Please.

Hi Guys im in need of some help here...

My stagea has developed a shudder through the steering wheel under heavy load when launching o. It doesnt always happen, and only happens in first or 2nd gear (standard auto still).

I have noticed its more likely to happen when i have the wheel turned, say powering out of a round-a-bout.

The shudder will continue through first and second gear, if i back off and then accellerate again it dissapears.

You can really feel it through the steering wheel, it gets a really strong vibration or shudder.

I thought it might have something to do with the front drive shaft or something, but not having a clue about the attessa system or 4wd for that matter, I dont know where to start.

Has anyone else had this problem or any ideas on whats causing it?

Cheers,

Ben.

try checking your cv joints onto the wheels. it seem to be it but have a look. If it is get it rebuilt by a specialist and you will save half of the cost of the new ones

read somewhere in another post that when the solders on the AFM becomes dry and cracks...when travelling on uneven roads the connections can move about slightly causing the car to jerk or shudder...then when on a flat road the revs become stable again...might be a faulty AFM which from what i hear is very common...doubt its the cv joint because when this wears out...the shudder or noise is quite consistent and doesnt go away. Dont know how a broken atessa feels ..maybe someone who's had this experience can share more.

my car has developed this cough when idling...happens especially when hot but the car revs smoothly when driving....really buggin the shit outta me...changed and gapped plugs to 0.813mm ..so definately not that

trying to go through the process of elimination too..so next week im gonna hafta clean the AAC and solder my AFM

anyone who's had this before would really appreciate some help.

yeah its defenantly not afm.

Its in the drive for sure, just not sure where yet! im gonna sneak it into the workshop and try have a good look underneath with the hoist and see if anything is visable.

I hate it when my car isnt 110%!!!!

Come to think of it...my car used to do that ...always in 1st or 2nd and when under load..eg uphill ascent...always thought it was uneven road...but apparently was caused by a faulty coil ...hardly noticeable but gradually reared its ugly head...solved now with some high temp silicone.

even if ur coils arnt shot...might be worth doing ...look in the DIY threads.

Hi peeps - I know this is an old thread and has been covered a few times but I'm concerned as my Stagea has developed exactly this vibration issue. I'm in the UK and the cars are a rarity over here so I'm trying to research this as much as possible before taking it in next week to get sorted. I've had the wheels balanced but it has not improved. I had the wheel alignment checked at the same time and they said that they set all 4 wheels parallel as per most other 4WD vehicles - but I have noticed some feathering on the front tyres since then. Was it wrong to get them aligned like that? It is in next week having a load of work done so I want them to try and sort this too. All 4 tyres are toyo proxes but the fronts are slightly less worn than the rears, could this be an issue? I've got a set of Tein SuperWagon Coilovers going on so they can have a good look around then - and I guess the suspension swap might even remove the problem anyway. Any suggestions would be really appreciated - I'll try to glean as much as I can from the other threads - but I'm not really technically minded so any 'plain english' (or plain ozzie) explainations would be great. Cheers peeps. :rofl:

Ps - I'm also having a Blitz down pipe, a GReedy Front mount fitted and the Turbo is being re-built with GT30 internals - looking forward to getting it back after!

John

    • Your stuff look much better than the original stuff I used on my tri-y headers, which didn't survive the swap, that did work OK though, but currently the headers are only ceramic coating, which, while it is meant to be the bees knees, it really only reduces temps by "not alot" and is more for protecting the mild steel pipes The new stuff is meant to maintain an "air gap" which "apparently" helps the insulation LOL In other news I'm taking it into Autotech next week for them to have a look at the RaceTCS, the spot where I want it, and the program "thingie" that is on my lap top computa which you would know as it is basically the same thing as your Racelogic  I'm really keen to get this fitted  
    • OK, a couple of questions arise. Are you suggesting that you want to swap to the S2 ECU so that you can Nistune it? Because....none of the R33 ECUs can be Nistuned. What would an ATESSA controller do to help? You have no ATESSA. Beyond that, the S1 and S2 ECU pinouts are nearly identical, as far as I can remember. A quick look around on SAU yields the following for S1. As I said, almost all of it is identical. I think there might be a few changes around the AFM and the ECCS relay, not much else. There's not functionally anything particularly different between a manual and auto ECU pinout. Can run a manual engine on an auto ECU quite trivially, for example.
    • Hey guys Was recently replacing the water pump and timing belt. Came across one of the washers for the timing gear and balancer were bent. Just wondering how that would of happened
    • Recently destroyed the front driver ABS wheel speed sensor on my ENR34 due to the iron knuckle rusting and seizing the sensor head. The other one on the passenger side has been soaking in penetrant for a few days, but I fully expect the same thing to occur. The wheel speed sensors seem to be specific to the AWD applications, and likewise the more readily available units from ER34s and S/Z chassis are not the same. An OEM unit seems to be available at $200 USD/ea, which is not ideal, but still fine. But if I'm in this boat in the future, those might not be available.   Does anyone know of any wheel speed sensor that uses the same head as the R34 GTR that could be used? Not overly concerned with cable lengths as wiring will be redone to accommodate PMU wiring.
    • Isn't this at least partially due to the way the dyno run was done? I'm used to seeing runs where they start as low as 1500 rpm to see how boost develops over the 2000-3000 rpm range. Seeing the torque curve fall on its face by 6000 RPM similar to this chart gives me some confidence that this run wasn't just entirely make-believe:
