Right folks meant to post up the solution to my problem but just getting around to it now. After a lot of trouble it turned out as dogma1 has said to be a Lambda Sensor, unfortunately it wasn't showing up in diagnostics.... Thanks to Paul Wray Motorsport in Strabane NI for sorting me out

Howya folks? Only recently bought a 2005 2.0 XT The car was lying up for a couple of weeks due to a wee ding, but since I got her back today I've had a strange problem. The Power / Revs are pulsing I can notice it when driving along the car is surgung/lagging/surging both when driving normally and when in cruise control Also when I'm sitting idling there is a slight pulse If I increase the revs to 1.5K she pulses around regularly i.e. rythmical (approx 30 times / min) If I increase the revs to 2K she does the same but a couple of more pulses per min And if I increase the revs to 2.5K, same again but a couple of more pulses than that Panel beater that repaired the car reckoned dirty injector, so I popped in a bottle of injector cleaner into half tank of petrol A buddy of mine has had similar problems with different cars and he reckons Throttle Body. I rang a car diagnostic Co and he reckons no point putting her on diagnostics unless theres an engine management light (which there's not) Anybody any ideas on where my problem might lie? Thanks in advance. Garry
