I have a 1993 R33 Gtst series 1 which I bought in June, the engine and ecu are completely stock (hard to believe I know) and the car runs completely fine... most of the time. About once every few weeks it will have a spasm and will not let me go past 2 and half rpm on any gear and jerks violently as if the revs are too high and just cuts the accelerator power once it tries to go past 2 and half rpm.

I am thinking along the lines of something to do with the turbo or maybe AFM, I was just wondering if this has happened to anyone else or if it is a common problem and if someone could offer me some ideas with with how to fix this problem.

Any help/ ideas/ input would be appreciated.

I have 2 videos I recorded today of this occurring but am unable to upload it as it is in mp4 format and am not sure how to convert it so it can be uploaded.

Sounds like an afm issue especially and the lower spectrum of the rpm. If you're handy with a solder you can crack it open and soldier all the joints inside it. Its not likely the element is damaged but more likely there's a cold solder in there. If that doesn't fix it then it might be a long road.

OP, post up a pic of the inside of the AFM if you want some opinions. The top of the box part is just glued on, bit of mucking around with a knife etc to get it off but not so hard. Should be able to see the problem if it needs a joint or 2 resoldered

it could be surging due to clogged injectors, run a $10 bottle of injector cleaner through your tank, fixed mine with similar problem and even if its not the problem at least you will have clean injectors

if it is the afm you may not see an obvious fault in the circuit board cos it could just be a dry solder joint so just hit each pad with the iron to make sure the pad is good, but i still think you should try injector cleaner cos it fixed my similar problem

No it's not a burn hole, its just glue.

So I ended up just re-soldering the 4 connection pins which you can see in the 3rd photo because I could see one of the pins looked like it wasn't connected properly. Hopefully this fixes the problem but it will be hard to tell because it was a rare occurrence in the first place.. so time will tell.

I like your idea of injector cleaner too Mick, I might do that as well since it's cheap and can't hurt by giving it a go also.

Thanks for your help gents, I'll let you know how it's going in a few weeks time.

  • 2 weeks later...

After re- soldering those 4 pins in the AFM I've been driving around Sydney quite a bit and the other day I drove Newcastle and back. My problem is fixed!

Thanks for the help!

    • That sounds like an excellent idea. But total self-sufficiency means exactly that. You have no-one else to blame when your system faults out and you have no power for a week or two while it gets fixed. You'd have to go the whole hog and get a diesel genny and all the switchover gear, to get you through such times. And, despite the fact that over 20 years, my system has been pretty reliable**, I have seen so many inverter explosions (or less dramatic deaths), panel and roof JB fires, and so on, over that time, to know that the stuff is the same as any other bulk Chinese manufactured stuff. The failure rate is well above zero - both on the equipment and on behalf of the meth addled installation labour force. And then..... warranty and means of redress against the supplier you bought the gear from. Best I can tell is that only a handful of solar companies are still around within 5 years of starting their advertising pitch. They disappear and phoenix like crazy. So, as per 1st paragraph, I suspect the only way to is go balls deep and spend maybe 2-3 times as much as you might think, so that you have every base covered. Plus, know and understand your gear intimately, so you can diagnose problems, sort them out yourself, etc, etc. Plus, probably have to consider upgrading various parts as the years pass, to maintain compatibility with newer stuff, performance and reliability, etc, etc. Whereas, remaining attached to the grid has an ongoing cost that keeps going up even if you use bugger all power from it. But it does provide the fallback in case of the worst case with your own gear. You either pay up front or as you go, I suspect.
    • Add more solar panels to the array. Call the electricity company and tell them you're moving out... Live off grid electric wise
    • Hi Jasmine. How's the war going?
    • I'm extremely suspicious of the VPP stuff. Best I can tell, you surrender any and all control of your panels and battery to the VPP, because there's no way that anyone could write a sufficiently useful set of "rules" as to how much you would be willing to let out of your export meter at any given time. If one of your main interests is to have enough in your battery every evening to get you through the night without having to import, you could easily find yourself with nothing in your battery at the end of the day, or part way through the night, and then be paying import pricing instead of paying nothing. I cannot see how this cannot come to pass.
    • majority aftermarket is an10 yes, but majority of OEM is An12 r35 OEM cooler lines at close to an 12, the hard line that car uses is almost 20mm  Porsche OEM is also AN12   i figure, if our power levels are close to 1000hp, then AN12 should be a must if many OEM standard power vehicles use AN12
