so basically im saying the stochiometric ratio is out which will make it lean not flat spot all the way.

i would still have it looked at but it may not be a fuelling problem for the reasons i have said. could be an electronic fault somewhere. mabye the mass air flow sensor is out or something and is not regestering how much air is going into the engine.



mabye try that first as its a 5 pound job just get one from a scrappy. im sure you can afford 5 pounds beforew you go getting the ECU sorted out.

interesting thought!!!!!the cams would have to be pretty nasty to increase the air intake that much that is throws the mass air flow out of it range or something but possible
