Okay. I've had an "intake manifold runner control valve stuck open" code for a while. Then, while driving, it developed an acute cylinder misfire. I was able to limp it home where I replaced the intake manifold, runner control, map sensor, and valve cover gasket. Now, I've got multiple misfires, the brake pedal is extremely firm, and the brakes barely work, and I still have intake manifold codes. The motor idle RPM is also increasing and decreasing. I'm at a loss at this point. Screen shots of the codes I've gotten and videos of what it's doing are included.
