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
