Code P 0300 and P 0301

Cylinder misfire- Cylinder number 1

Check engine light ON, Check engine electronics (on)
What i need to do?!

Find out why # 1 cylinder is misfiring.
Could be sparkplug, plugwire, coil connector?
Rather than guessing, you may want to have the engine hooked up to an oscilloscope, at a decent garage.

None of those.
Cleaning carburator fixed the problem.
Throttle housing was dirty. Now the car runs like new.
