Car suddenly started ideling very rough, very very rough accelerations and loss of power. Went to autozone and got the attached diagnostic. Im thinking my car is due for a tune up. Could any of you guys help me out with how to do a tune up and what I would need to buy? Saw a couple vids on YouTube but they weren't very thorough. Do you think it could be anything else causing these problems? Do you think this will stop the rough idle and acceleration? Will provide step by step pics and details if I am lucky enough to only have to do a tune up.
