Kangaroo under the bonnet??

**Steves-Vec** · 8th June 2009, 17:47

Hi i've got a 30,000 mile 06 1.8 sri very recently and it seems very nice and usually good to drive but suffers a bit off kangaroo-ing (non-tech) description obviously. But thats basically it sometimes when i lift off the accelarator it seems to kangaroo briefly as if i have put my foot rite down then lifted off but does then when driving pretty slow or mild. Not 100 percent sure if the last service is as stamped though and could be a little quieter so may change the oil to 5w 30 and new air filter incase its not breathing smoothly? Anyone else had or solved this type of problem?

Would have thought it would be running on 5W30 anyway?

At a guess, and everyone please shout me down, but crud built up in the throttle body???

Not sure yet as i say only had it a few weeks, hope its been serviced as stamped etc, will be getting decent service parts then getting a trusted friend to service and test run i think. Hopefully nothing more than a little build up as you say.

THe last car I had that done this was a 1.5 Nexia (First car)

It was a faulty HT lead..

Try sparks / coil pack?

Good luck

I've got the exact same problem in my 56 plate 1.8 sri too, and its also done 31,000 miles. Would be interested to see if anyone else has had this problem before and what the cure was. Don't fancy booking it into vauxhall as more than likely they'll return the car with "no fault found"

Also got this problem on my 2.0T sri. Only just started doing it. Am going to do a minor sevice, air filter, oil and filter and plugs in the next couple of weeks.
Will let you know how it goes.
