Omega Engine Managment light Staying on

[Tornado632]

Hi Guys

Just changed my exhaust down pipe on my 1999 20l 16v ecotec Automatic, started the car and it ran rough for a bit but now its ok, but the engine managment light is staying on... Can I bring up the flash codes by using the paper clip trick or is my car too new! I seem to have two diagnostic plugs, one in the main fuse box and one next to the servo unit, can anyone tell me which is the correct one.

Yes, and its one under steering wheel.

The one on suspension turrent isn't a diag connector, its the cruise control loom.

As TB says you can paperclip it, instructions are below

have you checked that you've not disturbed any connectors possibly the lambda sensor as you've been working nearby  :-/

Hi

Yes I have, when I first started the car after fitting the exhaust is was runing badly, but now its runing ok so I think the fault is gone but still stored in the ECU and only need to be cleared to put the light out..
