Hello gents, been away for a while as I sold my mk3 20vt. Anyway I got this little beauty for £220. I had to tow it away from the seller as a non start.he told me he changed the dizzy cap and it wouldn't start. I got old dizzy cap off him fitted it and it fired up and cut out, after some tinkering i Checked key and found usual chip had fallen out. I used spare key and it fired up! But it has a misfire under load. I found when pushing car in 4th gear there was a hiss from the spark plugs. I sprayed wd40 and found bubbling up when rocked. So changed the plugs cleaned seats and added hylomar to threads and it stopped the leaks. Only thing is is still misfiring under load. If I rev it gently it won't misfire. I see you guys always say plugs, leads, cap and rotor. But is there anything else common? Cheers
