Hi. Sorry i didnt get back to you. I telephoned Kitchens Renault in Burnley. Explaining that im only getting 27mpg Ave. and that at 120mph i develop a Miss fire.

They said bring it in we will hook it up on the computer,and i asked them to change the plugs at the same time.

The plugs were not renault. They ran the test with the new plugs in and told me that my compression ratios were good.

I filled up the tank and reset my trip computer. on a full tank i averaged. 35mpg and i can now take the needle to 130mph without any miss fire.

So for me my problem is solved. Decent Fuel economy and smooth Top Speed.

Hope this helps.

Regards Gary.
