If everything dims, check the ground connections near the battery and also near the alternator. I don't know anything about the check engine light.
with out checking the motor vehicle for loose front end aspects, it may well be perplexing to assert what the probelm may well be. it must be someting approximately waiting to permit loose on you nevertheless, to the place you will possibly lose your guidance thoroughly, so it needs to be looked at ASAP. there may well be a ball joint, tie rod end, or different front end area that's bent or failing, and extremely practically waiting to permit loose thoroughly it could additionally be the means guidance rack itself that is going undesirable, or a tire loose (lugs loose) or a substantial subject with the wheel alignment or balancing of one or the two between the front tires. despite if it isn't the tires themselves being loose, that's uncertain, then i might lean in direction of something having way too plenty play interior the front end, from placed on. a different choose for instant prognosis!
P0172 means the air/fuel mixture is too rich. When you are accelerating and then all of a sudden let go of the accelerator, the air intake valve will close causing a high vacuum pressure in the intake. What's important in this situation is that the computer needs time to go from accelerating to idle. While it's doing that, the engine will be running rich while in an already rich situation. Essentially your car is flooding. It could be faulty spark plugs.
