G60 Losing power

[993turbo]

My 90' G60 is losing power. The best way to describe it is like its the car is powered by a 30 hp engine. It does not rev up, and it cannot handle uphills.

Symptoms:

No misfire, No overheating, No strange sounds, No uneven running, it just lack the power / torque.....The car idles perfectly and starts perfectly.

What has been checked:

-The obvious vaccuum leak locations around the intake and hoses to from G-lader - intercooler - intake.

-The airfilter and fuel filter is new

-The spark plugs have been checked they look very good, not wet, not black, they are like a text book example. Rotor and dizzy cap looks good.

-Full opening on the throttle body is achieved when fully depressing the gas pedal.

Do you guys have any hints or tips on what to check next? Fuel Pump?

What else?

Any oil in your inlet pipes / charger outlet / intercooler?

When you say checked boost hoses, how have you checked, may be worth sealing then and using an airline and soa to check for leaks.

is the power intermittent, a-la belt slip?

no blows from the exhaust / manifold?

checked the timing? its pretty much identical to doing it on a normal digi2 8v.

checked the vacuum line on the back of the inlet manifold to the FPR and the vac hose to the ECU?

Sounds like fuelling problems.

No oil in the inlet pipes...

The power loss is constantant, like if it was a 30hp engine.

What do you mean by BLOWS from exhaust / mainfold?

I have not checked the timing

All vacuum lines checked......... also up to the FPR / ECU.....

yeah, it smells a bit like a fuel pump issue to me, cause the engine runs so fine at idle etc....

There's a vacuum line which has to be precisely a certain length to the ECU.  Have you replaced this at any point?  I know this can cause odd behaviour if it's not the right length.

This line must be 100cm. Not changed. The car was running fine, and now suddenly its not.

is it makeing the boost it should ?

Dont know. I have no boost meter in the car........

I can also add that the loosing power thing is a lot worse when the car is cold. Then is has hardly no power at all. Sounds like a fuel issue to me, or.....................?
