Just looking for some insight on some help with this issue. Just got my Ka rebuilt (stock, for now) and when "trying" to drive it tends to sputter , cut out and backfire around 3k. Idles around 900-1k. Thinking maybe injectors problems ? Or spark plugs ?

3 k is usually MAF sensor if it doesn't want to rev passed that
Coolant temp sensor often causes running rich/backfire

I would check those along with timing
