hey guys his the situation...i got to the servo tonight to fill up and when i got out of the car i heard some weird hissing sound from the engine bay, i opend it up and traced it to the hose connecting to the boost gauge thingy, now i just got this car so im new to turbos so excuse me for how i explain. now i notice the tip of the rubber hose was split so i tryed taping it up with electrical tape and the gauge is reading abit different so im guessing some air is leaking...what i want to know is, can i replace the hose, can i get it from like autobarn or somthing, and if i drive it the way it is will it effect the car in some way. thankyou so much for you help.

Cut off the hose where its split, and simply plug whats left it back into the factory map sensor for the boost gauge ,if there's not enough left just get a new hose, you will find it starts at the rear of the balance tube.... it's dangerous to drive around with a line such as this that has access to the atmosphere, unlimited boost.. bang there go your turbos and maybe engine too. And on engine vacuum it will suck dirt and shit straight into the engine bypassing the air filter.

all good, i took your advice of cutting it and i re-attached it. its so tight now and its reading better then before so must of been a tad loose. i drove it for about 500meters until i noticed it was f*kd do you think anything could have gotten in or would somthing have already happend? thanks for your help.

Yeah Oakliegh mechs got real good prices,

and nah lol, your engine is fine, worst you would hav got was a vacuum leak, but if its split where the boost guage is, it will only affect the boost guage reading

i had the same problem with my 33 when i got it. i just cut the hose but about 2 weeks later it broke again so i got a new hose.

as for what moodles said about it being dangerous to drive around with it off, that isn't very true. yes it could suck some dirt into the engine which is bad (but it could only do this at idle or low load), however it will not cause unlimited boost, and when you are on boost it will actually be blowing air out that tube, so no dirt can get it. also it would be making low load run a bit lean, but at higher load, such as when it is making boost it will actually make the car run a bit more rich, which isn't a bad thing other than using a bit more fuel.

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
