Cars over fueling bad! Help please

[ntcupra]

Cars over fueling and don't know why, I've got a 4 bar fuel pump and a 4 bar pressure reg I've changed the pressure reg and still having the same problem, is there anything that I can try??

Any help would be great, thanks

Injector stuck on? got any codes?

 

[ntcupra]

Injectors are fine mate, went to have my new turbo mapped in today but can't cause of the over fueling issue

 

[ntcupra]

No codes, mapper said go on vag com and in to block 31 and the reading should say .4/.5 on idle and mines on .8 can't remember what it was called sorry

 

[ntcupra]

Anyone have any ideas?

How was the vagcom reading?? That fpr ok??

 

[ntcupra]

Still the same mate so it's not the fpr, so I got a spare now

 

[NAB_ARCK_86]

I got a spare set of injectors if u wanna try that

 

[ntcupra]

Craig was saying its not the Injectors :/

 

[ntcupra]

Going to have a play with the car tomorrow just need to get some ideas what to play with

 

[NAB_ARCK_86]

If its fuel related i imagin its fuel pump fpr then injectors that all it can be surly

 

[ntcupra]

Remember the pipe that comes off the inlet mani that I snapped the nipple off managed to make it not leak but now it is, I still haven't put my new one on lol so that's leaking vac a little and if I remember rightly that makes it idle funny so going to look in to fitting the new pipe tomorrow

 

[NAB_ARCK_86]

[ntcupra]

Ye but couldn't that give a shity reading?

 

[NAB_ARCK_86]

Dunno maybe but i dout it

what spec of car?
turbo, injectors, map

whats 001 block showing? what faultcodes? (lambda malfunction in circuit for example)

 

[ntcupra]

Turbo dynamics ko3 hybrid, standard injectors and a revo stage 2 map

Just plugged my code reader in and got this code
17511 P1103 O2 Sensor Heating Circ.,Bank1-Sensor1 Output too Low

But won't that show up as I'm over fueling?

Changed the injectors today just to see if that makes a difference going to plug her in to vag com later and see if that's sorted it

 

[ibizacupra]

given your car is narrowband, how are you judging its over fueling?
you cannot look at lambda on 031 to make the judgement properly. Its only narrowband lambda

you have'nt answered the 001 block reading whilst its "too rich"

 

[NAB_ARCK_86]

Craig measured somthing on block 31 bill and it was on 8 when should have been 4 or 5 on idle?? Thats what nathan told me, we changed the fpr yesterday no diffrent injectors today seemed better befor he left me its 100% over fueling it sticks, pops and bangs all the time and i spitting black **** out the exhaust
