Running Rich..?

[swiftymcfeat]

Hey there,

On saturday i went and picked up my new VL

Just been keeping an eye out for any problems that may occur and i can smell a fairly strong petrol smell as if the car is running way to rich... Im new to VL's and dont know much at all so im asking for help here! haha

From what i know, its a VLC turbo with an n/a conversion (p plater friendly)

Ill get a "my car" thread going soon enough :P

Cheers and hope u can help...

UPDATE:
So i have now fixed my exhaust leak and blown dizzy and its honestly running like a brand new car. But the fuel smell is still there, maybe even worse. MOST of the time you can small it fairly strong inside the car and sometimes can even smell it when standing outside the car after driving.
My fuel usage is much higher than it should be.

----------------------------------------------------------------------------------------------------------

UPDATE 2 - ERROR CODES!
These are displayed (along with the others that are meant to be)
11 Crank angle sensor circuit
12 Air flow meter circuit
21 ignition signal circuit

ANY IDEAS/SUGGESTIONS???

-------------------------------------------------------------------------------------------

UPDATE 3!
Found where the fuel is coming from! Im not all that great when it comes to engine work but from what i can see the injectors are all surrounded by leaking fuel. Enough to cause the smell that is getting me high on my hour long drive to work! Here is what im talking about:



I also following the guide on how to adjust your AFM and i turned the screw half a full turn clockwise to try make it leaner. Did not really make a difference though?

My car usually smells like petrol sometimes, but not too often that I worry about it. It runs fine regardless so I don't think anything is up. Is your smells always there?

[87RB30VL]

BTW, nice car

[swiftymcfeat]

Well yea it gets pretty strong, and there is a fairly noticable leak/hole in the exhaust up near the headers which is causing some problems (im hoping thats the cause, if its not i wont be happy haha). Once i pay rego ill patch it up and go from there i guess.

Thankyou, i cant wait for CFC this year haha!

[87RB30VL]

re-reading your post, I wonder if it has anything to do with the turbo-to-NA conversion that was done on it? I don't know much about fuel injection, but could it be possible that there were larger injectors installed, and once the turbo was removed etc, the injectors are squirting too much fuel in?

See if it was a carby I could probably sound like I knew more since I know more about carbies :P

[swiftymcfeat]

It is fuel injected, and i THINK he put an NA engine in, rather than removing the turbo from the existing engine. I really need to obtain more details when purchasing cars haha. Well ive withheld the last bit of the payment untill he gets a few things that he promised so next meet up ill get what info i need haha then update my post.

Just been keeping an eye out for any problems that may occur and i can smell a fairly strong petrol smell as if the car is running way to rich...
.

What colour is the exhaust?

[detox_nath83]

search the forums for running rich man... its been covered plenty of times....

nice car love the color...a few things can cause running rich problem...

it could be the vapour lines from the fuel tank have split hence the strong petrol smell... have a sniff in ur boot and around your back seat/behind rear wheel under the guard,,, i wont call u an abo either,

[jatsvl]

petrol smell is usually as detox_Nath has said around the back of the car near the wheel arch, it could be vapour lines also if it is in the engine bay check your fuel in and out lines also the little rubber hoses to your injectors.

What colour is that cobalt blue????

[swiftymcfeat]

Purple with blue pearl through it mate. Ill get some better pics up with time haha

[swiftymcfeat]

Updated my op. Still need help!

[jatsvl]

so if the smell is inside the car I would suggest it is in the engine bay, so you need to check all the fuel lines and follow your nose, the smell will get stronger the closer you get to the source.

Check too see if its running 3ta or 3tm ecu. My bets that he has ripped the turbo off and put n/a headers on it. What colour are the inectors? They will either be brown or a tan colour

Ill check the headers tonight after work, but im fairly certain he did an engine swap and put the NA engine in rather than just removing the turbo. I suppose he could have left the old ECU, i mean he did not bother putting the heater or air con back in at all haha

[swiftymcfeat]

Had a sniff around the engine and it just smells too strong to know where its from... Im fairly certain its coming from somewhere towards the back of the engine. I gotta figure it out im getting headspins!!

set ur afm back to factory so u dont get a lean out... have u fixed your leaking injectors?...

these codes "could" be old codes stored so clear them and run a diagnostic again..
go over all your plugs/sensors and give them a shot with INOX/Contact cleaner/WD40 etc even pull back the rubber boots and check for corrosion on the crimped spade connectors... then process of elimination man

[jatsvl]

all of your injector hoses and clamps have been replaced go over them with a flat head screwdriver and tighten them up that will probably solve your fuel smell.
people usually replace them when they replace INJECTORS.

edit; your cooling system bleeder bolt has corroded and snaped off, so whats in the hole?

[Pub247]

air flow meter almost always cause rich lean running as they tell ecu how much air there is and then ecu put in x amount of fuel so if AFM reads more air than there is then ecu will put in more fuel than needed.

Get that leaky injector fixed too looks like the hose from rail to injector is leaking

[detox_nath83]

good spot justo... looks like the bolt thread is still in there
so not good cant bleed that high spot only one on the plenum....

make sure u fix this man

[swiftymcfeat]

Will be replacing every hose and clamp along there 2moz. One doesnt even have a clamp! Hour drive home i swear im high as ####!!!

Ill keep u posted

Thanks all!

[jatsvl]

some pointers.

perfect circles!

[swiftymcfeat]

Thanks for that! My silivour tastes like fuel! Bleh!

[swiftymcfeat]

All injectors and hoses to injectors got replaced today. Running great! Got half way home, starts running rough, and dies. If i start it its like its running on 1 cyl. Now im stuck on m4 waiting for a ####ing tow!
