My vehicle listed above started throwing these codes 2 days ago while I was driving home: intake manifold runner control stuck open bank 1a, crankshaft position sensor A circuit, random/multiple cylinder misfire detected. The traction control lights also came on at the same time. The intake manifold code popped up on my car before, months ago and my ex replaced it and said it was fine and that it must just be a sensor and I had no problems until now. When the codes came up, my car felt like it was struggling to accelerate the rest of the way home. I then got new spark plugs and my car drove fine after that for an hour drive. Then I went to drive again, and it began to do the same thing but intermittently- the lights would come on for a second and it would struggle to accelerate, and it would last maybe a minute max and then go back to normal for a little while and it kept repeating this. I then bought fuel injector cleaner and drove the rest of the way without issues. The next time I used my car, however, the lights came back on, and it is struggling to accelerate again more frequently. When speaking to a friend, she told me that she had almost the same thing happen and that it ended up being that she needed new brakes- which I definitely do need new back brakes and have for a while, they sound awful. I just don’t see how that would correlate to the codes but it is weird that the traction control lights come on when it happens.

To me it sounds like you have a throttle body that needs to be serviced. But we should get the code numbers, so we head off in the right direction to fix the car, here are two guides to help us see what's going on and how to service the throttle bore for your car in the images below.
