Loss of power on full throttle = limp mode

[SteveX]

my car did this for a while,
i replaced the 2 O2 sensors, and the airflow meter.

problem solved

Thanks, it's possible the cats and o2 sensors have been damaged by a rich mixture I guess over time.

In previous vehicles where I have seen an o2 sensor failure an engine management light would normally come on, not sure on the CLK though.

Appreciate the input
