Why is my Vectra misfiring? 
            
            
                I've got a misfire on my 2001 Vauxhall Vectra 1.7. Sometimes it's fine, others, it's struggling to go. Any ideas?

                        Presumably the old Isuzu 1.7 diesel engine, so the problem is likely to be one of the injectors. If it's clogging you may be able to cure it simply be adding a fuel system cleaner to the tank and filling up with shell V-Power Nitro Plus diesel.

    I own a Chrysler Voyager (2000 model). When travelling over 3000rpm, it leaks oil over the top of the dip stick. It has also developed a misfire. Any idea what could be causing this? 
    
    
        
    
    My Skoda Fabia is misfiring. A mechanic has cleaned all three spark plugs and checked the coil - both are okay but still it is misfiring. What should I try next?

                Far better than previous Vectra. Now with decent handling and an excellent ride. Plenty of safety kit. Roomy in the front. Big boot. Good looks.
