My Maestro 2.0EFI is extremely lumpy when in low revs. I need to drive in a higher gear than what I should do just to make it driveable. Idling can also be lumpy, I intend to change both ECU's and the idle bypass valve, if that's not the solution what else could it be ?

You can usually clean out the bypass valve as they can get gummed up with crud. Worth a try! Also check the rotor arm doesn't rotate on the cam (the bush often deteriorates).www.maestroturbo.org.uk - The Tickford Maestro Turbo Register
