Not Corsa.... but Astra. I'm 99% sure my 2002 Astra Cab has a z18xe, but if not please feel free to correct me.
Basically when cold my Astra idles lumpy. It sits at normal revs but you can almost feel the car shaking due to the lumpiness of the idle. It'll then rise to near 2k revs for a second or two, and then settle above 1k before calming down below the 1k mark. If I try and drive off too soon after starting it the car will almost feel as if it's about to stall, meaning I then try for more power only for it to rev up and move like normal.
I'm thinking air flow meter? But if anybody else has any ideas I'd be greatful.

Would the pedal test only give warnings if the EML was on? As at the moment it's not on, and hasnt been on for ages. Not since I had a bew lambda sensor fitted.
I'm going to have a proper look tomorrow

Cleaned the throttle body, still doing the same thing. Had a look at the AFM, but tbh there's very little to inspect! Might just take a punt on a new one anyway.
