I was wondering if anyone could shed some light, I bought a 16v anniversary and got it running but it won't idle, it will run quite happily with revs on the throttle but then dies when you take your foot off. I have replaced the dizzy, plugs, leads, rota arm and ignition coil with no joy. I've taken the ISV off, cleaned it and refitted, no change, I have taken the throttle body off and cleaned it, no change. I have unplugged the ISV and no different, it dies with revs, I have checked the voltage at the plug to the ISV and it's 12v and it buzzes when plugged in. Anything else I could try please?? Limited mechanical knowledge so please be gentle 😂
