I have searched the forum with no luck to my question for help.

Well. This is the beginning of hopefulness. :-)
BTW. This is a carry on of the wife and I project scoob.

I got the car back from the auto elecs. They said it started. I could
not replicate it at home. Nor could they when I fetched it for some
or other reason.

Anyway. The verdict was that I had to source a manual ECU with matching key, antenna and immo ecu as autos are non existent.

Anywho. Got all that. They plugged it in and no more fault codes.
So far so bad.
They apparently managed to start it but could not get it to rev higher than 900rpm.
After much faffing with it at home. For some reason it decided to splutter some life this evening. By life I mean less than 100rpm. (Im sure they only got it to 90rpm. Not 900...) It is very erratic and there is no difference if I depress the throttle. Other than cut out.

So far I have pulled the intake manifauld of. All looks good.
Checked the TMI for blockages. Turbo spins up like a hurricane. There is spark. (only took out one plug to check with on all leads) There is fuel. There are no fault codes. But it wont idle and normal RPM. Let alone rev.

Does anyone have a clue with some pointers.

I need with this car.
