VP Idles Fine - but dies on acceleration

[h8itear]

Great site BTW.
I have a VP Wagon(lexcen) 92 140,000kms The car idles fine but on quick accelleration dies! Revs with a squirt of aerostart!!
On slow acceleration the revs build successfully - throttle position sensor ok.
Its not showing any fault codes - more on this later.
Fuel pressure is right on the mark (pressure tested) - fuel regulator functioning.
Tried new MAP sensor. New water temp sensor.
As for Fault lamp in dash - lamp is working but not showing any faults (only 12) even after disconnecting MAP sensor and/or temp sensor while running.
Could my ECU be dead/dying?
If so any idea on price/availability on these? - I live in Melbourne.
Any help would be greatly appreciated. Thank You

coil problems?

Have you checked the 3 ignition coils.sounds like some sort of secondary ignition problem.

Thanks for your reply!
We checked spark consistency through a timing light, and also checked injector pulse.
We have narrowed it down to a fuel issue, specifically a lean out at open throttle.
I've got a feeling its the ECU as no fault codes are displayed even if I intentionally create a fault.
I'm still at it this morning - It aint gonna beat me!!! :b:

Found the problem!!

Thanks for your reply.
The problem was the ECU, I got hold of a changeover for $170.00 - running better than before.
