Lexus Forum - Lexus Enthusiast Forums - Lexus GS350 cynlinder 6 misfire help!!!!

What’s up everyone I have 2007 Lexus gs350 I got a check engine light and my vsc light came on as well for cynlinder 6 misfire (p0306) the check engine light does flash I changed the coils and put new spark plugs in it ran good for a little while then thru up the same code I swapped coils to see if the problem followed and it just stayed the same cylinder 6 misfire and runs really rough I’m having a compression test done on it soon just trying to see where to go from
here or if anyone has had this problem I was told it could be the motor or an injector also someone mentioned Seafoam any ideas thanks
