New VR6 owner, having problems!!

[Charlievw 0]

Hey,

Ive recently got my VR6 and seem to have a few issues. I done a search on the forum and nothing seems to cover my problem.

The red hand brake light seems to come on when driving, but generally when its a bit cold and damp/raining. It does seem to fade away and go when the engine gets warmer and after a while of driving.

But my main problem is that when i drive the car hard, it seems to bog down massively and loses loads of power towards mid/upper rev range. I also noticed that the engine sounds like its missfiring/running lumpy anda few puffs of black smoke comes out of the exhaust.

Funny thing is when it does this and the engine starts to lose power and runs ruff, the red hand brake light starts flashing while its happening, then when i change gear and drop the revs back down it goes.

Could this be an ignition fault?

Any help would be great?

Thanks

mmmm dont think its ignition , mine has been on for a few months now , i could not clear it , i am going to remove my brakes and check all the sensors ect , might be abs cable

not sure on the bogging down though ,you cleaned Maf ect?

No, how would you clean it and would you use to clean it?

what year is the VR mate ? I would say its maybe the coilpack or as said above worth cleaning the MAF and throttle body as good cheap easy places to start to clean the MAF you need isopropyl spray or electrical contact cleaner ( can get them from Halfords) just remove it and spray loads all over the sensor inside but dont touch it ! with the throttle body can use carb cleaner and again just clean off any gunk from around the butterfly valve

Ok,

I took the plastic throttle bodie elbow of and it was all gunky and oily inside. Would this be from the Rocker cover breahter?

Gave the trottle bodie a clean and took some crap off the butterfly.

I also realised that the reason why the light keeped flashing on was because the little plastic part in the cap of the brake fluid resivoir had poped out and was making it seem like there was no fluid in it. Light has now completly gone out when driving.

While i was moving stuff around near the trottle bodie i noticed that when the stainless 6 branch manifold was installed someone must of ruited a hose wrong as the the smallish hose coming out from just behind the trottle bodie has melted and made a large hole in it. The hose looks to be a breather and go to a black lump of plastic (maybe a large valve) which then looks like it head down towards where the fuel lines come from.

Could this hole in that tube cause the problems?

Thanks

well its not gonna help things mate

[vr6stormt 0]

it is the carbon cannistor valve tube it will run lumpy if you run it with a hole in as it will let air in you can just block it off like a lot of peeps on here

[Ben Seabrook 4]

yeah as above sounds like the carbon canister mate if so just block it off and yeah that wont be helping - block it off and take it for a spin

so cut the hose where the hole is and bloke both ends of the pipe yeah?

[Ben Seabrook 4]

just cut it off before the hole and block off the end that runs into the block mate - the other end you can leave

Done as mentioned above and it seems to have helped.

Although Since i cleaned out the trottle bodie and intake system the other day, its now taken a little longer to start, and sounds like it isnt firing maybe. Do i need to reset the throttle after cleaning it out?

Thanks

disconnect battery for 15min and then try that

also if the problem continues try finding all the grounds and cleaning them up

I managed to get my VR6 odb2 up against another ob2 vr6 yesterday and notice that im missing the pcv valve coming from the rocker cover to the plastic inlet pipe, and instead i just have a bit of pipe.

Would this be cuasing me problems?

Thanks
