Technical No Power - Same Problem

[goneleft]

Hi all.
My Cinq is still way down on power especially up hill or accelerating in higher gears. It just never gets to a decent amount of revs.
Anyway so far i have changed:

- Plugs and leads
- Coil Packs
- TDC Sensor
- MAP senor
- Idle Stepper Motor
- Throttle postion sensor
- Injector

I've had all the pipes to the the throttle body of numerous times and last night i swapped the ECU for a non coded 6F version. No difference. Except now the warning light thats a picture of a key with the word code under it is now on. Will this be solely due to the fact that the code box can't get a signal from the ECU or is it related to something else?

Also if the cars idleing and i disconnect the input to the stepper motor should it make a difference? Or if i disconnect it and blip the thottle? I wonder if the replacement could be a dud.

Got a compression tester on its way to check it over at the weekend as well.

Cheers
EDIT: 899 Cinq '97

If the car is down on power, but generally running OK, I'd expect some kind of compression issue.

I'd do the test before you spend any more money.
