Q: Misfire on cylinder 3
When the RPMS raise past a certain level, usually around 2500, or when accelerating quickly or to highway speeds, the vehicle throws a code and begins running poorly. Code is showing a misfire on cylinder 3. I've changed the ignition coils, spark plugs, and inspected/cleaned all fuel injectors. And based on visual inspection there seems to be no leaking around the intake manifold. However the issue still persists. Any suggestions on what else might cause this?
