Omega General Help / Aircon, coolant leak and sluggish accelleration!

« on: 13 July 2010, 03:26:09 »

It's all go (or no go) for my 2.5!

1st crisis as the weather is so hot is that my aircon is not working. Could this be related to my external air temp sensor not working? Put a new one in yesterday and still no joy. There must be a break in the wire somewhere, but the Haynes manual is no help for tracing it's path to the ECU.

Coolant is also disappearing at about a litre a month. No idea where.. No mayo in expansion tank.

Also engine sluggish under hard acceleration until the revs hit 4000 rpm and then it's off like a greyhound. Is that normal?

My previous car was a BMW E30. Lots of space around the engine (straight 6) to see what's wrong and to get to bits.

Any help graciously received

Omega General Help / Lumpy lack of power under load until 4k (2.5 auto)

« on: 14 August 2009, 01:28:08 »

Can anyone help?
I have a petrol 2.5 V6 auto and when I boot it, the engine becomes rough and lumpy and lacks power until it hits 4000rpm and then it's fine. It's not a "power band" thing. Is this some kind of air flow issue? This problem happens about 80% of the time when I gun it. Any ideas folks? Much appreciated!

Ta, Scott

Where is the best place to post photos of what happens when a shiny VW golf side swiped my '99 Omega Estate?
