Injector Corrections Continued, New Injectors??

[bigjohn333]

The Saga Continues...

The car is a 2001 406 2.2HDI 4HX Engine with 106k it has a remap but the car runs the same with and without!

Things I've done so far

- Changed all the injectors
- Changed the "bad" injectors
- Tried a combination of "new"and old injectors together.
- Changes injector seals (copper washers)

The problem seems to almost exclusively lie with cylinders 2 and 3.

Cylinder 1 I've identified as being at the bellhousing/flywheel end of the engine.

Still poor injector correction values see pictures.

Rough running at idle, lack of power until turbo spools up, poor poor MPG! 28.9mpg!

I'm thinking mechanical, compression? Valves?

Thoughts, comments, reflections?

Not sure on the flow rates. Low compression will either be rings or valves. Could be the head gasket gone between 2 and 3 cylinder. Do you have access to a differential compression tester? With that you should be able to pinpoint the leak
