Car Got Stuck On 9000 Revs Without Me Doing It

To cut a long story short. Was driving today and the car seemed to accelerate without me making it. I pushed the clutch and pulled it into neutral and the engine reved quickly up to 9000 by itself and stayed there until i was able to cut the power to the fuel pump (luckily i have a kill switch). Im guessing that the accelerator cable got stuck but it seems fine and im worried that it could be caused by something else - maybe turbo/boosting related? I wasn't driving the car hard at all when it happened.

what would cause the engine to spike to 9000 revs and stay there? besides the accelerator cable/pedal getting caught or stuck.

my car seems fine now but im scared to drive it without knowing what may have caused it since the cable doesnt seem like it had anything to get caught on.

any help/opinions would be appreciated.

i've had a loose throttle cable slip off when the throttle was half open and stick like that, then be back in place by the time i stopped the car and lifted the hood. If the throttle body is closed, the engine cant rev. It has to be the throttle sticking somewhere

Or a hose.

I had some hose get loose and get jammed in the throttle body.

I forgot to use a cable tie after i was changing the plugs or something and it moved in the way.

No harm done

Same. The hose.

Was mid burn out, started getting out of shape, backed off.... hose says no.

For reference, its not lucky you have a kill switch, everyone should be aware you can simply turn the key off, throttles getting stuck is not that uncommon, don't panic, just turn the key off.

Careful with the key, too far and you will be dealing with the steering lock.

Or just go up a gear, 4th to 5th and jump on the brakes till you cna sort out turning the ignition off.

Thats what i had to do as i wasnt sure what was going on.

It isnt good for the car, but the rev limiter is there and does the job, but better than getting too outta shape.

I'd rather f**k a clutch than have somethin bad happen

My story is good.

The same thing happened to me. Nailed it at the lights and then the throttle jammed open somehow, car rocketed down the street, evetually switched it off and rolled to a stop. Upon inspection, the f**king trumpet from my GFB Bov had unscrewed, and jumped across the engine bay coming to rest under the throttle lever leaving it wedged fully open :kiss:

I made sure I screwed it on extra tight afterwards. Seriously though, what are the chances of that?

Don't you have to take the key out of the ignition before the steering locks?

dont think so, if the cars off and you move the steering wheel to far to either side it'll lock it with the keys still in the ignition.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
