hard to say, is the fuel pressure good?
have you had the codes checked?
a dyno tune will cost heaps & they may not even do it with it running so poorly.
i think get it checked by someone with some experience in this particular model.

It's kind of hard to explain. Of late 50% of the time when you go to start it first thing in the morn, It might loose revs and stall. Then the pump will buzz for 10 seconds, then start it up and it's fine. It drives great it's found wanting at times for low power like it's slipping but it's not. Then the burst of speed in the middle rev range is like a turbo boost. It idles fine when your driving it really runs fine, Park it and the idle can be a touch off, If you lift the bonnet you can see looking at the engine it's missing a touch. Then if you turn it off when it's warm and go back to it 5-10 or more later the idle is sick till you drive off.
Even when there seems to be a loss of power it will not chug like it's missing when you are moving, It doesn't seem to run rich but it's getting more like 400km to a full now when before it was more 450km. It doesn't smoke or stink of fuel. Then i might have a day or 2 it's like it's old self?.
I reset the ECU 2 days ago and it started like it always did perfect. Next day back to it's sick self on cold start. I also changed the throttle body i forgot to mention.
Cause i got a sports system and done all the other things i mentioned i was told i might need the tune, But how expensive is it
.
I'm going too see a friend who is a mechanic this weekend he is going too have a look but i have this filling it's ecu or coil pack as it's up and down.
