Check engine light after fuse 20 removal, what's wrong?

Hi guys,
I removed the fuse 20 in order to reset the ECU (after new standard plugs changing)
Right now, the CEL would come up after around 20 miles driving.
Reset the ECU by pulling fuse #20, and after around 10-20 miles the CEL would come again.
CEL never come up for years on my car. Last time was when my DI cassette gone south replaced around 20k miles ago.
I notice a bit high idle (around 1.0 - 1.1 k rev) before CEL comes. Didn't have chance to connect to read fault code yet.
Question : What could go wrong with this kind of symptoms? would pulling fuse 20 cause or manipulate things gone wrong like this?
Please enlighten. TIA guys
