I replaced the coil already, But no it doesn't overheat or knock or anything. All of the gauges stay the same. I keep leaning toward it being a fuel related issue because it runs fine cruising under 60 and as long as I don't reach 3,000+ rpms.. Its like when the car requires more fuel at higher speeds that's when it starts to misfire really bad, like it cant keep up if that makes sense. Almost like the combustion chamber isn't getting fuel sprayed in there everytime like it needs to be and causing it to hesitate and feel resistance and bog down. Sorry im trying to type it where it makes sense lol
