Welcome,I have been a master mechanic for over 35 years and am happy to help you with this.See if you can narrow it down to one cylinder by removing one spark plug wire at a time and see if the engine idle changes, either runs worse or stays the same. if it stays the same it means that cylinder is not working properly.Try that and get back to mep.s dont get shocked :-)
