I own a 2002 pt cruiser last week saturday night i was doing 70mph on the freeway and there was a little missfire for a few seconds, it stop later a few blocks away from the house the car turn off ,but start again no problem
it was 3 am so i didn't check anything next morning it was ok

today in the morning the car turn off at a red light and later it was missfiring and lossing power i made it home but the car didn't start again it took 10 minutes trying

now it turn on but missfires like crazy rpm jumps from 400 to 1500 i am sure when it gets cold in the morning it will be fine


my question is what can this be ? where can i start looking for the problem ?

thank you for your help or any ideas
