Why is my malibu idling hard while stopped at a red light?
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.
I had it scanned and the error was saying misfire on cylinder 6. Change spark plugs wires and coil. Still didnt fix it my next option was maybe fuel filter. To it to a actual mechanic today he hooked a pressure gage to where my cylinder 6 spark plug is and no compression if he aint screwing me over he said it will be headgasket or value. 1,200 to 1,500 dollars
