[s-cars] Stumble/PowerLoss Redux

[Douglas Fifield]

On checking the Bentley, it points to:

- Fuel system pressure too low
- Spark plugs, ignition coil, ingnition POS malfunctioning
- Leakage in exhaust system before CAT
- Incorrect signal for MAF

For advice, it says to fill the fuel tank, repair the leakage, check
the fuel system, check the fuel pressure.  Hmmmmm.

There is some visual evidence of rich running. There is a faint tinge
of soot around the exhaust on the rear bumper.

The hose from the turbo to the MAF is suspect where a hose clamp has
cut partially through the rubber where it clamps to the crankcase vent
system.  Wouldn't that make it run lean though if it was sucking air
in while in a vacuum state?

I spose it could also signal that the fuel pump is on the way out.
The only way to check that is by splicing in a pressure guage, right?

Come back,
