Hello,

I have problem with moving off with cold engine. If start cold engine (after 12 hours standing), I cannot increase rev and car twitches. After approx. 1 mil problem die down. Should I change spark plugs?

And second problem is with chatter. If I have idle speed I hear some chatter noise and I feel that engine litle swing.

Have somebody these problems?


Thank you very much, Petr.

My VTS is a bit rough on low grade fuel.
Runs a lot better on high octane fuel.

Mine played up a bit like that, went to my local Citroen garage, they put my car on the computer. Twice it's been on it and they found nothing. Any I went out for the day and I needed more fuel so I went to Sainsbury's and put some in and my C4 has been fine since. So I now run it on Morrison's fuel and it's been good for a month. So try that mate.

Thank everyone for advices. I tested high octane fuel but with any improvement.

I will try to call local dealer for reflash ECU like Rich wrote in their topic.


Thank everyone.

The easiest way I can describe how it behaved was no matter how hard you pressed down on the accelerator, the engine speed would only increase at a predetermined rate until c3000rpm at which point it would then shoot off....

I had that on my 2.0l VTR+ ... never kept it long enough to find out what it was.

I'm a regular user of supermarket petrol (and now diesel), normally going to Sainsbury's as a first choice and Tesco as a second. Third choice is Texaco, just because they have a reasonable loyalty card scheme - better than Shell's anyway.

I filled up once in my last car (petrol) at the Morrisons in Enfield, and alas it was enough to put me off using their petrol again. The car really, really didn't like the stuff, and didn't so much drive back up the A10 as bounced up it as it coughed and spluttered. Definitely 'watered down' compared to rival supermarket dinosaur juice.

Have run my last two car's predominantly on Sainsbury's petrol and both were bullet-proof in terms of reliability. Since I got the C4, it's been filled half the time at Sainsbury's, once at a Tesco and once at a Texaco.
