so yesterday i ran diagnostic mode on the ECU and it came up with 55....no malfunctions

i ran a bottle of injector cleaner through the system and the car started spitting out all sorts of carbon build up and the idle seemed to calm down and wasnt so bad

3 of the coilpacks have cracks in them so i need to replace those, i took it for a drive and it started sputtering and backfiring and even though the idle has evened out a lot it has a misfire every now and then and when you rev it up, plugs could be fouled as well, need to check them
