Why is my malibu idling hard while stopped at a red light?

文本:

two day ago i got gas.  after getting gas my car starting to run hard when in drive and stopped.  I put heat and injector cleaner in gas thinking it was water or trash causing the problem.  my engine light came on and scanned it only error was a bad spark plug on 6.  it seems to run smoother when in park but when in drive it idles hard.  and has a ticking sound from motor.  is this all from bad spark plugs,  is transmission bad, is it a fuel pump, or a bad motor due to the ticking sound?  I plan on changing the spark plugs and wires first but dont want to tear up my car driving it till i find out whats wrong.  let me know what you think is wrong.
