help ? has anyone got any suggestions please,
My gtv has had the maf,cam belt, air filter, plugs & oil etc. in the last 6 months, its just starting missfiring at low revs and the injection light goes on & off at will, today whilst sat at traffic lights the engine suddenly revved to 2500 and back all on its own WHATS GOIN ON ????? Module reset required ??? any ideas please
It's worth checking the plugs, new or not one (or more) could be faulty and they'll show any signs of an engine running rough, they should be a nice biscuit colour. I'd check the leads and the fuel filter too.
If I remember correctly I had revving problems on my Corrado and I'm sure the hall sending unit was to blame, which could be the problem for the misfiring also, being that the hall sender controls engine speed.
checked the plugs, they are not biscuit coloured, but clean, look nearly new ?? what about a crank sensor ?? plug bores are clean & free of oil & water
If you do a search for 'idle actuator' there are similar threads to this
mine was replaced once and cured phantom revving
