When driving the DB9 it has no power under load.
except for P1000 there are no DTC's.
Im puzzled what could be the issue. when revving the engine in N or P there's no issue to get it to 3500rpm.
However when attempting this while driving it has no power. Up to some 2500 rpm it appears fine.
Fuel pressure is about 270kPa relative to manifold when connecting the reader. Also when driving. Though it gets hestitant as if it doesn't get enough fuel.
plugs and coils are new. Injectors have been cleaned and tested.
It has run most of its tests, but no coastdown so no misfire monitor. When seated I can't feel any misfire in the seats.
Any ideas where to look?

 

Recommend if you haven’t already, check the throttle bodies and make sure they’re clean (had a similar experience not too long ago and they were the cause).

 

Yes, TB's have been cleaned. And just redid just to be sure.
Also checked vacuum at the fuel pressure regulators. This showed -0.6 bars (17.7in Hg) at both. While running perfect.
After doing this I went for a short drive. And got P2198 (bank 2 sensor 1) and P2106 (bank 1). It sounds exactly as if 1 bank is not doing much when it goes wrong. Which could be explained by P2106.
Weirdly enough all the other instances I got not DTC's at all.

 

Have you checked the exhaust for blockage? Catalyst damage can occur quickly, secondary (not monitored) can fail and cause restriction. Which will definitely cause the problem. Easy to remove to inspect.

 

2198 means its too rich, or just a bad 02 sensor, have they all been changed? I recently got that code, changed all 8 sensors, car is running perfectly.
