My 2006 gs300 awd Lexus first started running rough then vibrating and started to plutter then I went to leave & it wouldn’t start but crank over it not the battery that is good so left it alone two days later I try starting it again and it started right up then plutter out & died & hasn’t start up again but cranks over a friend told me it was the fuel filter so I called to get it fix and was told there wasn’t a fuel filter in this car so now I’m confused & don’t know what to do or how to even find out what’s wrong with it because I can’t drive it to know shop have any ideal..?
