So my car works totally fine under 60mph and under 3k revs but as soon as i get to highway speeds and rev above 3k my CEL comes on and it blinks slowly then stays solid and will run just fine but a bit shaky. When i come back down to low speeds the engine will shake horrifically. Until i turn it off and on again it’ll run like nothing happened and the CEL goes away. Any thoughts?
