Hi I have a 98 integra b18b1 turbo and I’m having an issue with my throttle having this almost like dead zone where it will just jump up and down . As you can see Hondata doesn’t pickup any input but my foot is on the throttle lightly and it just jumps up and down . My throttle cable adjustment is okay and my TPS calibration on my tune is where it should be I’m not sure what is causing this please help

don’t mind my exhaust leak I know it sounds terrible

Sounds like a vacuum leak
