Could be a long list of things causing the poor idle. Strongly suggest you take it to a good mechanic to get it looked at properly.My friends Virage V8 starts but wont idle below 2000rpm, it seems to be running very rich as plugs foul quickly and sooty exhaust. Please help me by suggesting some ideas. Also how do you remove door panel as I need to get to central locking motor. Thank you very much in advance.
