Spark plugs changed but still a feel slightly shakes. Today i have unplug Maf sensor and start engine CEL light but shakes exactly the same. When clear ECU and plug MAFS CEL gone. Is it possible that ECU doesn't show any issues on MAFS but maybe it is broken.

It is possible it happened to mine. I had replaced the MAFS with one from a scrap yard but still same thing happened so I changed a bunch of other stuff idle control valve plugs coil packs. Ended up changing the MAFS again and like !Removed! magic it was running fine. But I know it's not cheap to replace :(
