2012 equus multiple misfire codes

[jonny89z24]

Hello, I got a 2012 equus , ran good up to a point where I gad to let it sit for about 8 months, now it had codes for a misfire on cylinders 3, 5, 7, and a random misfire code. So thinking it would be odd for multiple spark plugs and/or coils to go at once, it might be the high pressure fuel pump for that entire side of the fuel rail, but no codes related to low fuel pressure are showing up. I did add new gas and stuff to clean the fuel injection. Anyone have advised?
