okay people im in a real problem here. I have a erst s2 which i have had the CO set twice on it. The problem is after one or two days the CO goes lean which at that point it starts to miss on idle but through the rev range it seems fine i dont what it could be but its pissing me off. Also the car wont rev over 5000rpm so i cant get it rolling roaded. Anyone been through this

 

metering unit had it?, fuel filter blocked?.

 

fuel filters new i think the metering unit too but not sure any other way to find out

 

not sure wot else to suggest, everything connected up properly?, id try a metering unit, they do go, my mate had a similar problem to yours with his CO and it was the metering unit.

See what the others suggest

 

cheers mate will try the metering unit

 

Just thought of something else, that black fuel injection ecu on the blukhead, could be that, they have a cut off thing in them i think for the fuel when i high revs are reached, they are normally cheap to get hold of aswell.
