What if I changed all 4 spark plugs and all 4 coils and still having the same symptoms....shaking and both check engine light and trac light

Hi Justine! Did you replaced with original coils? Sometimes chinese aftermarket are not good and it would not work.
You could also have a mass flow sensor dirty or complete damage. It can be clean with mass flow air sensor cleaner wait until it dry complete then install it back. You can buy it on auto zone for $6-$10.
Also, I recommend to check the motor air filter. If the filter is dirty it needs to be replace.
Hope this helps!
