Ka problems

[gue399108]

Ok so I have a ka and when I rev it and hold it at any rpm it starts to kinda wanna die out. The rpm goes die and up and die and I'm just holding the pedal. Any suggestions??

I meant down and up and down*

My SOHC does something like this on a cold start, but it will idle fine for like 30 seconds then it completely dies out, sometimes it stumbles then dies, so I've tried holding the gas pedal it will still die
