not holding boost and can smell fuel when i boot it.

[joe_thompson]

We basically my cars not boosting right, it seems like it drops off boost, and also doesn’t seem to boost up for what it should (18psi)
I can also smell fuel when I put my foot down for, this is only if you put it down for over 15/20 secs. I have no idea what it could be :S
I know iv got a blowing inlet manifold, iv just picked up a new gasket and studs so should sort that out tonight but surely that would cause it would it?

My cars a 02 ibiza cupra, cat back miltek, forge D/V, pipercross induction, P-torque remap, phampton boost gauge.



Any ideas?

I've heard the smelling fuel before... when's the last time the fuel filter's been changed?

It's a suggestion. Mine's smelling of petrol when I drive it hard (for a 1.4 ) and a couple of other threads have suggested the idea. Did you search before you posted?

a friend of mine had the same problem we checked all to fuel lines took the tank out sealed every joint and it stopped for a little and came back again turned out that it was the fuel cap it turned out the small hole that was ment to be in the centre that not been drillled right through so he drilled the hole right through and so far problem solved all i can say is get a new cap

16486-mas air flow sensor (G70): signal too low...could be making it overfuel maybe...or could just be that the pipercross filter has fooked it...

i had this with mine, i changed the n75 valve and the boost stated holding again.

try that or check out the actuator, mine leaks boost when it hits 15psi

 

[joe_thompson]
