Hello, A few times I've noticed this now, I assumed I was doing something weird the first few times or imagining it, but it's definate now... Anyway, my 99 corsa 1.2 16v (zoom.....) occasionally has a loss of power at about 2k-3k rpm in first gear. It accelerates, 'hangs' for a second with no rpm increase, then carries on as normal, the rest of the gear changes are fine. Has only happened three times so far, under heavy acceleration from some lights, it only does it from 'luke-warm' eg after a few miles. Doesnt do it straight from the drive way and doesnt do it after many miles. There seesm to be no definate pattern... I've even tried to do it deliberately to reproduce it so as to get some more info, no joy so far.
Seems like it cant be arsed to inject anymore fuel for a second then goes "oops" and carries on. Anyway, not life threatening, just curious and if its something I could easily fix with a hbol as its a bit annoying when it does happen...
cheeeeeers Barry
