re. Fuel cutoff- what triggers it?

[Swann, Benjamin R. (BSWANN)]

Taka,

Except for the readout on the Boost Guage, it sounds like you are hitting
the overboost protection.  Check/replace all hoses to the wastgate,
particularly the lower wastegate hose.  The one in my car looked in all
respects good, as the cloth wrap wa fine, but the hose underneath had
disintegrated, and it came apart completely when I went to replace it.  I
found the problem using a vacuem pump/guage.

Puzzled about the boost guage readout though.  Let us know what you find.

Regards,

Ben

Hi listers,
I've encountered a rather interesting problem.

The car in question is an '86 5000CS quattro, MC engine.

My car won't rev past 4400 rpm, at which point the fuel
cuts off and the car jerks rather violently.

The car feels _much_ more powerful recently, all the way
up to 4400 rpm.

Boost gauge in the trip computer won't go past 1.2 bar,
although it would do 1.4 bar previously. Throttle body
hose is in good condition and less than a year old.

Any ideas?

Thanks,
Taka
