Questions and answers

I've got a 2016 Honda Accord that's been a trusty daily driver for years, but recently I've noticed the engine feels a bit rough at idle and there's a slight hesitation when I accelerate from a standstill. The car still runs, but it definitely doesn't feel as smooth as it used to, and my fuel economy has taken a noticeable hit as well. I'm not a mechanic, but from what I've read, rough idle and hesitation can be signs of worn spark plugs, especially if they haven't been changed for a while. I checked the service history and I'm pretty sure the plugs are overdue, so I'm hoping that's all it is. I'm based near Musaffah Shabiya and I'm looking for a reliable spark plug replacement service in Musaffah Shabiya that uses genuine parts and knows how to gap them properly for the Accord's engine. I know this is a relatively straightforward job, but I still want to take it to someone who will do it right and check the ignition coils at the same time, because I've heard that if the plugs are badly worn, the coils can sometimes get damaged too. Has anyone here had a similar issue with their Honda and found a good workshop in the area that did a proper job? Also, roughly how much should I expect to pay for a spark plug replacement on a 4-cylinder Accord? Any advice would be really helpful because I want to get this sorted before it turns into a bigger problem. Cheers.
