Sometimes when I drive (maybe twice a month, but right now almost every day), the car decides to ignore the throttle and the revs get stuck (at around 2000), the car won't stall, but it loses acceleration and will be jerky for a while, like it struggles to move. I can give it full throttle and nothing happens, then after a few minutes it goes back to normal. Doesn't matter if the engine is cold or hot.

Throttle body cleaned, throttle relearn done, spark plugs changed, ECU reseated next to the battery.

I suspect the MAP or Lambda sensors (these sometimes give me some strange graphs), but I'm not 100% sure and I don't want to waste more money on this issue.

Also, sometimes completely out of the blue with the car running without issues the engine light goes off and I get a Catalytic converter error code.
