Hi there.

I have a vectra b 2000 w reg 2.0l dti ecotec engine.

I noticed sat in traffic the other day thet the engine managment light was on, and on acceleration the car seemed to have lost a bit of power. The light comes on and goes off. I drive it to work on the motorway and it was doing 80mph no problem but it took a while to get there and I could not get it over 3000rpm in 5th gear. Starts fine. had no running issues at all until the other day.

Someone has mentioned the MAF or EGR valve.

Anybody got any ideas...? Thanks in advance.
