G60 Losing power

[DarnPB]

DarnPB, now your over here, why dont you get to these guys http://www.g-werks.com/Contact/1/Default.aspx one day, as they'll give you the best info on where the problems may be. Have a health check service, rather than a full service or something.  It might point 993turbo in the right direction too, once you find where the problems are.

That is my plan one day when I get the time. Work is very hectic at the moment and I have to juggle my time between here and Spain, as my family are still out there.

Ok, got the new Fuel Pump. Installed the pump, but no change to the problem :-(

 

So, the following is new, or has been checked:

-Fuel Pump (New)
-Fuel Filter (New)
-Air Filter (New)
-Vacuum Hoses Checked and changed
-Boost Hoses Checked ok

The car idles perfectly, but does not rev up properly and has no power.

I did an Compression test just to get an idea of the combustion chamber status. All 4 cylinders perfectly lined up around the 150psi mark. In my book this is good. I did not bother to perform a leakdown test as the numbers were so even.

I will check the timing belt, if it has ''jumped'' a tooth, however unlikely due to the smooth idle.

Does anyone have a good description / pics of the marks on the crank - cam?

Further, I will do a check on the iginition timing.... This seems like a hard job with the intercooler etc in place.....

Any other hints and tips...?

Cheers for the timing info... Great Stuff!

Any other ideas on the loosing power issue?

Do you get the same readings as this guy? http://www.youtube.com/watch?v=6bswDjsmP_w
.6 bar (atleast) on the G-Lader.

Have you disconnected the lambda yet and gone for a drive? The lambda connector is on the passenger side down by the exhaust manifold. Just pull that off and tuck the loom away, then go for a spin.
My next job is to clean the injectors in an ultrasound bath. I've tried everything else.

I have checked the Timing Belt acc to the info in the links above. All settings line up: Cam wheel - Crank - Dizzy.........

I get 0.6 bar at around 2500rpm, and this rises to about 0.8 at 3500rpm... So this seems fine!

Yeah, tried to disconnect and drive the ECU into ''safe'' mode but no change.....
