Spark plugs (and coil?) replacement Kia rio 2012
I have a Kia Rio S 1.4L Petrol 2012 model that had a coil misfiring yesterday. called out the roadside assistance and the guy was super helpful. he said I need new spark plugs and that the reader said that coil number 2 was misfiring - causing my engine light to start flashing and the car to be a bit shaky. he did a thing where he tapped the top of the coil so that the space between where needs to fire was smaller, which has fixed the issue temporarily, but he stressed that I still need to get new spark plugs.
I don't have a lot of money at the moment, so I'm wondering if anyone has any tips on replacing the spark plugs (and the coil too?) myself or for my father who could also help. any advice on the brands or models too could be really helpful.
thanks!
