I have a 2003 Punto Mk2 1.2 8v, just replaced the head gasket following major blow and had the head skimmed 7 times to get it flat! Rebuilt the car and cleared out water etc that had got into inlet manifold. When I start the car it immediately revs up to 7000+ rpm and chucks out loads of exhaust so I have to switch off immediately before blowing the new gasket! Ideally I'd like to run in the engine gently! Tried removing and cleaning throttle body but no difference, tried unplugging TB connectors but no difference, seems no matter what I do it's determined to rev like crazy once started. When I removed inlet manifold during head removal I did notice what looked like old sealing compound around some of the retaining nuts/studs - I replaced the manifold green rubber gaskets but does it need additional sealing? Any ideas welcome!
