0Hi again i tryed this in the engine section a week or so ago but to no joy.
Just replaced my head gasket as i thought this may be the problem but now im swaying towards something electronic.
Basically to cut a long story short My astra coupe 2004 engine z18xe starts but will not rev, it has got no fault codes stored or present when running the only thing i notice that has a slight glich on normality is when OP-com is on measuring blocks with the engine running it is saying throttle position invalid when reved although it is fine on idle it says idle on log. also i have no milage display or the other display (clock+temp etc) heres a copy of log to help explain;
