Hi guys im a fairly new person on her so much help would be good as im new to corsa' aswell. I have a corsa b 1ltre 3cyl and when i got it it was a write off, i rebuilt it and after a couple of dayd the engine management lite came on and it was really sluggish and flat spotted, got it checked the egr valve had gone, changed it and now it still flat spots and is sluggish, i have recently put an induction kit on specific to the 3cyl from k and n. It now flat spots occasionaly at around 50 under hard acceleration and the engine management lite comes on briefly and goes off and then the car pulls again.


Heeeelllllllpppppppppp!!!

Air Mass/Flow Sensor gone? Try cleaning the connections. Check for any air leaks in the air trunk or vaccume pipes. Get any erratic idle or pinking?

I have no engine management light on any more, and there is no erratic idle.

Probably like my 1.2!

Requires new AFM, Coolant Temp Sensor, Modified loom and plugging into a comp and re-mapping!

Not cheap if it is the common problem some 1litre/1.2's have!
