Check engine light ON
and if so best to have the codes
most local part store should be able to help you in getting the codes and or rent the tool to do so
recheck firing order and check coil too
do not over lock the fuel pressure
let me know what u have for codes

If its a misfiring than it should show up on the scanner
check for pending codes and check misfiring data to identify cylinder s
