Ka24de problems

[emileeoh]

Im not getting any power after 3000rpms. The harded i press on the throttle the less power it gets. People told me its the MAF and i replaced it and it still did the same thing. Anyone know what it can be? Please help. Thanks

Check your ecu for codes. If you don't know how search it. Also check the wiring at the maf. Make sure the connector and wires are in good shape.
