2007 Honda Accord

Sup everyone, so im trying to sale my son Accord. We got this car like 5 months ago from a friend with a vtec problem. So I ended up fixing that problem an now another problem occurred. I don’t have the time to fix on the car anymore. The car starts up an drive but it showing misfire when you run the code. I damn near changed ever sensor on this car. New coil packs, new injectors, new map sensor, new spark plugs. You name it I changed it. The mileage is pretty high due to the previous owner using it as a daily to work. So as you can see this car push me to the breaking point, now im trying to sale it an get my son another car with a easier problem to fix. Looking to get $1,500 for the car.
