Title: 2.2 16v Rev Drop underload
Post by: seanjones on 31 August 2010, 08:31:40

Hi Guys,

I've just come back from my first batch of motorway driving with my omega, and have noticed a weirdness. Under hard acceleration, in sport mode, there is a slight dip in revs after changing up. Basically the following happens:
[olist]

• Stand on the gas with the sport button pressed. The car pulls well
• Car shifts up, hits 3500-4000 rpm.
• The revs drop slightly(200rpm), as if I've backed off the gas for a second or two
• The revs build again, and off we go.
[/olist]

I do currently have a blowing manifold, which ticks away however hot the engine gets, that I haven't yet had the courage to fix.

I've never had an auto before so I don't know if the above is normal, or related to the manifold or what. No EML btw.

Any one got an opinion?
