I was thinking in my limited knowledge. Would changing the spark plugs and air filter make any difference rather than the $$$$$ it will cost to replace the CAT and Lambda sensor?

2002 Toyota Yaris failed MOT. Fast Idle test reached 2220rpm with a minimum of 2500. The garage want to replace lambda sensor and the CAT but is there anything such as air filter and sparks I could try first?
