NEED HELP ANYBODY!!!!!!

[p66rider]

Hey, just got a couple of queries. One minor and one major, although they could be connected ? :S
First things first, the minor:
About two months ago, my Engine management light started flashing. Although i had no problems starting my car, it drove fine and when i connected to diognostics, nothing registered. So i read up and aparently it means there is an imobilizer fualt. Although there is no problem starting the car and it drove fine. So i ignored it ! Just wondering if somebody had encountered this before.
Second thing, The MAJOR :
About a week ago i started my engine, went down the road. Went to change gear and the revs started rising rapidly and my foot was off the pedal. I panicked and quickly turned the ignition off. When i started the car again, after checking for any cable sticking. The revs jumped to 4000 and then returned to 1000 but was jumping between 1000 and 2000 consistantly. I then turned off the ignition left it a little longer and it started fine and didnt happen for sum time after. Although recently it has become more persistant and while driving along the throttle wont close and it continues to accelerate, i thencut the engine off, while moving and bump it and it either corrects itself or jumps between 1000 and 2000 revs with the clutch down or i lose throttle reponse if its up (throttle doesnt engage until pedal is halfway down and then it engages. I have tried the obvious: checking for vacuum leaks, cleaned throttle body, changed air mass sensor and lambda sensor. But still no difference. I think i can rule out a sticking cable, as if it was, then surely the revs wud not jump up and down and would not correct itself by the disengaging the engine.

This has really confused me and any help would be appreciated.

Ihave the exact same car as you. and my engine management light comes on well all th time. not wen i fist start but aftr like 10 mins or so and stays on then off and on. Means nothing if yours does that. You major problem. not a f**k clue

[p66rider]

nah its not like that! It just constantly flashes with the ignition on, it doesnt come and go ! :S

i would clean and check your idle control valve and your throttle positioning sensor mate.

[p66rider]

ok, it just happened again although this time, i lost my brakes aswell. The pedal became hard as if there was no pressure in the servo :S
Its getting worse !!

[matty101]

sounds to me like its more of an elecrtical problem you've got not mechanical. think ur ecu cud be goin loppy or somthing. bluecorsab is the uy u need to talk to

[p66rider]

Ok, I swapped the throttle bodies over, from my old corsa and would seem as if problem is solved, although the eml is still flasing, so I tried swapping the ecu over, but it would not start and I had the original key incaase it contains a transponder! Any idea?

[donnay1991]

u can still use the key from ur other corsa if it fits as long as ur original key is near it. take off the plastic around ur steering wheel where the ignition is. its like a sensor thing of if the key close. we did it at college

[p66rider]

yer i had the key quite close but does the transponder work with the car or the ecu ? like if i change the ecu do i need the original transponder or one that was with the new ecu ?
