This may be due to a lack of fuel to the engine causing a lean running condition causing this misfire or an issue with a restriction in the exhaust components itself.If these have not been checked to see if any of these are the cause here this needs done and if a fault is found it will need repaired to correct this issue.A fuel pressure test needs checked when it acts up with a fuel pressure test gauge attached while acting up as well as an exhaust back pressure test done.
