Mazda Repair: miata wont start, new spark, maintenance work

Question
sometimes it starts after trying lots of times. just got my spark plugs replaced and worked for a week then it started to not start again. when it does start i have to keep revving the engine to about 2-3k rmp so it doesnt just die. feels like theres something in the exhaust like the engone is flooded. i just got a new battery. it works fine if i get a push start and start it in second. then it works for a day then doesnt want to start. it usually dies when idling.

Answer
Sounds like you may have multiple overlapping issues with this car.  I need more information to help you though.

Did it start and run fine with the addition of the new spark plugs or just better
How many miles on the car
What year

Recent maintenance work besides the plugs?
