1990 integra ls. 198k 5 speed feels like it’s not getting the power is should be getting then once you hit 4K rpms it feels like you’re hitting boost and have all the power back. And sometimes when I’m going up a hill it feels like not getting enough power or down shift it will throw a code and randomly. but it won’t read when I jump it or it just blinks a code 30. I’ve replaced fuel filter and fuel injectors it’s had a valve adjustment. So lemme know what you guys think.
