what? the r33's? if you say so..........

on my r32 the doesnt lock till the key comes out.

steve

My R32 locks with the key in it, but it does have to be in the off position.

When you first shove the key in it how do you unlock the steering wheel?

I am required to turn it to the acc. positon with a little wiggle of the steering wheel. I would think if locked once they key is slid out then it must also unlock by simply sliding the key in.

Thanks guys, nah, i just thought someone went happy modding on me.

I suggested that cutting the fuel pump is not a good idea. especially at 9k rpm.

Motors have been killed by a fuel pump failing at wot. Cutting the ignition would be a better idea.

Yeah that was exactly the point I was raising. I don't think cutting the fuel is the best way to stop an engine running at 9000rpm. Don't be a custo, just turn it a little way, its not hard to feel the first click in the off position with no steering lock. Interesting topic though, seems a few people have had similar issues.

One time a padock basher brumby I had, got throttle stuck open, but then went one better, kept going once key was off as it was running unleaded fuel (when it shouldnt have been) and the little thrash had it pre-igniting. so ignition off, then it kept going, so i slammed it into 4th and pulled the hand brake on, it tried for a little then died....

dude you arnt going crazy, theres a second post thats exactly the same in a differant section!!

i went through it and though the mods cut sik at it, but i guess they havnt spotted the second one.

To update:

The problem remains and this time i paid more attention and it doesnt feel like the throttle gets "stuck", but it feels like it actually accelerates and opens up. I mean it feels like the throttle just opens up itself. Both times it happened I was going pretty slow and accelerating in second gear at very pretty low revs.

I spent yesterday making sure there were no cables, wires etc near the throttle cable and accel pedal.

The whole cable and throttle spring/mechanism etc feels excellent - no sticking or anything.

Also had a look inside the throttle body at the butterfly valve thing and it seems to move fine and not be loose or sticky. Lubed up the cable so it couldnt stick and did everything I could to basically make sure the cable or throttle mechanism had nothing around it to interfer.

Then, after driving the car around for over 2 hours, it happened again. Was in second gear and was starting off slowly... revving maybe 2000rpm in second gear and accelerating slowly - then it felt like it was accelerating harder and i took my foot off the pedal and it kept accelerating, took it out of gear - revs shot up - i killed the ignition, stopped, looked under the hood at the cable and it was free and restarted and the car was fine.

I have the older rb20det NICS type and thing think it has something to do with the idle mechanism... i have no idea how it works but i figure something has to give the car throttle when your not touching the pedal so that it idles... and maybe this opens up or gets loose or something.

In this post -> post http://www.skylinesaustralia.com/forums/in...howtopic=124145

someone talks about a faulty aac valve (?) and a valve UNDERNEATH the inlet plenum/manifold that adds air according to coolant temp based on maps in your ecu.. (?)

I'm really just taking a stab in the dark - please help!! I'm really stuck with what to do.

or just takle it somewhere to get it checked :)

perhaps the return spring(s) are broken. both on the pedal and on the throttle body.

also the tps has a spring too. it would be hard to put it on backwards though

The AAC at maximum open will only hold your revs at around 1600....not 9000. If the throttle is shut...the car cannot rev. Your problem must be throttle related. it is physically impossible to increase the revs that much but not allow any more air to enter, the engine would choke and die.

Does the accelerator pedal return to it's normal position when this happens?

Do you have any kind of cruise control fitted to your vehicle?

no cruise control

and i think the pedal felt like it was stationary... To be honest it all happened so fast that i could be wrong - the pedal might have moved... i AM sure that it wasnt stuck. And i AM sure that when I stopped the car (like 1 second after it happened) the pedal and the throttle mechanism were both in the usual position and not caught/stuck or in an unusual position.

what about the cold idle valve?

    • Had a go at the stuck crush tube this afternoon. Tried things like grips and a chain wrench first but wouldn't just twist straight off. So got to work with a drill. Started small and kept a depth stop on to make sure I didn't drill into the bolt. Made a line of drill holes all the way up and enlarged them. Then a combination of chisel and Dremel to split it all the way up. Levered the split to get oil in there and eventually it gave a bit while levering. Worked it back and forth with loads more oil till it was spinning freely, then with grips I could work it downwards and off. And no significant damage to the bolt (not by me anyway - just the 27 years of rust)
    • Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days  - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains.  The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.
    • It sounds farrrrrrr too cold at your place Duncan... Here I was thinking our 10 degrees overnight is getting cold...
    • oh yeah, reminded this morning....bin lids frozen shut too
    • In my case not, because of total reno. But yeah.
