I think I have found 90% of my issue,
This red pipe had come off the round topeed thing (Actuator I think), I put thi sback on and it seems to be running a whole heap better I can start it from cold and it will hold its own without intervention although it does seem start bogging down after maybe a minute of running.. give it a blip on the right foot and its fine..
The Plenum.... I found the wires as mentioned and they have been affixed here but I have no bolts to fit so I can resolve this in a few days.
Then I also found this... I would hazard a guess at an earth wire or sensor.. but couldn't see a spare wire hanging around.
The turbo is a Garrett but I couldn't see then number, I was working whilst it was snowing so I wasn't getting on the floor and that also explains the whit stuff you see everywhere..
I also found it had a metal gasket on the exhaust manifold but forget to check the block (Dumbo
I left it running for about 20 mins or so and then took a cautious drive around the block a couple of times and I have almost no kangaroos now but still not quite right.
This was my gauges after a run and it should have been plenty warmed through.. Do these look about right?? (I know its hard to say)
This is going to sounds odd but that red pipe that had come off.. would it have caused the knocking sound as now I cant seem to hear it...
