2009 Suzuki Swift recurring check engine light

Hey Scotty,

My girlfriend has an automatic 2009 1.5l Suzuki Swift with around 180,000km (110,000 miles) mostly highway, and the check engine/emissions light comes on and off intermittently. It had a collapsed cat 6 months or so ago which I replaced and prior to that the coils were replaced along with the spark plugs. Every so often though, the check engine light will come on and stay on for a day or so and then disappear again. 

What are your thoughts before I start needlessly replacing stuff? Thanks from Australia.

You need a scan tool. Scan that thing and see what the hells going on. GL!
