Toyota Vitz Check Engine Light Issue

Ive been trying to figure out why my cars check engine light keeps coming on, and Id really appreciate some help understanding the problem. This issue started a couple of weeks ago when the light would randomly appear while driving but then go away after a few seconds o r minutes, and the cars performance remained the same. I had the wiring and some other minor things checked, but it didnt solve the problem, and the light continued to come on and off randomly.

Then, one day, the light came on, and the cars acceleration ped significantly, not going beyond 20-40 km/h. I had it checked the next day, and it turned out that one of the spark plugs was burnt out. The mechanic replaced the spark plug and the ignition coil, and this fixed the issue for a few weeks.

Now, the problem has resurfaced, and when I got it scanned, it showed error codes related to the throttle body and exhaust system. The mechanic recommended cleaning the silencer and catalytic converter CAT.

I havent had that done yet, and I wanted to ask if this cleaning could be the reason for the recurring check engine light?

The check engine light is basically there to let you know when somethings not quite right with your car. If the scanner has found any error codes, its a clear sign that theres an issue. You can also do a quick Google search to get some basic information about what those fault codes mean.

Dont forget to take a look at your cars battery terminals too. Make sure theyre not loose.

Once youve gathered all the information, start addressing the problems one by one. First, look into the throttle issue, and then consider cleaning the catalytic converter as the second step.
