So I considered the air intake gaskets. When I opened it up.... my goodness the carbon soot around the air intake cover and the engine ports was so bad, you couldn't slip a 10cent piece in it. Cleaned them up as best I can using a carbon removal spray specifically designed for diesel engines.
Now after putting the engine bits and pieces back together again and to see how it runs ... the car won't start. It turns over but won't ignite. Faults did come up on a scan one was fuel pressure low the other cam position sensor low reading. This was after connecting the battery again. So I cleared the faults but no start still remains even though the faults have not come back up again.
So I bought myself a volt meter and tested the cam position sensor. There are 3 wires on the sensor connector signal = ground = voltage. I'm getting 5v on the signal wire, but zero reading on the voltage wire. This is with the sensor removed just testing the adapter.
So I'm confident the carbon soot blockages was the low power issue, bur I can't test it out with this new cam sensor issue. That's if it's a faulty cam sensor or wiring.

Yes, the EGR soot combined with the
PCV oil produces a sticky bituminous glow that builds up everywhere on the intake system downstream of the throttle body.
With that model, if the EGR system gets blocked, say by a piece of metal (maybe cut out from a tin can) accidentally falling into where it joins the throttle body, you'll get no codes, no check engine light, and no more glop blocking up
the intake.
Fuel economy will improve a little though.
Just saying...
