• Jerking 93 Astra 1.4i 19 Apr 2003 (Forum)
  . The problem was really bad ie it was jerking in every gear and even when not accelerating. I have changed the spark plugs, changed the fuel filter and ran a bottle of engine cleaner in with my fuel. I think the two latter things have helped to solve the problem and now it only does it when my engine is cold
• Astra diesel cold starting 3 Dec 2002 (Forum)

• Golf mk2 GTI 8v or 16v 22 Nov 2002 (Forum)
  I am thinking of selling my Carlton and getting something that doesn't gobble as much fuel. Also the complexity of the carlton and stuff going wrong is beginning to scare me. So, having sold my trusty Golf CL, I want to return to the fold but with more power and luxury. Clearly a post '90 car

• Oil Additives - Any good? 12 Jun 2001 (Forum)
  is in them is any good, the oil producers would be putting the stuff in anyway. By the way, adding Wynn's Deisel Clean to the fuel hasn't made any difference to my car's fuel economy or performance (present 53,000 miles). Any thoughts? Tom
• Excessive Consumption 23 May 2001 (Forum)
  to lay out £50 or so, only to be told "It appears to be within normal tolerances" (ie"we don't know enough to find out what's wrong"!) - I'd prefer to spend it on fuel! On the other hand, if it IS 'over-fuelling', I'd obviously prefer to get it fixed - if it CAN be! So, you Ford/diesel experts - can you

• VAT increase 14 May 2010 (Forum)
