2006 ES350 - I had 2 coils replaced under warranty. The dealer tech rep said it's a common problem. I asked if I'd be in there 4 more times, or can they just replace them all now. His response was "well we don't know which ones will be bad". I was a little PO'd after bucking up for a lexus to hear this is a common problem (I had other issues with this specific dealership, so I'm always irritated with them). Had a 3rd replaced after warranty was up, just went in for a 4th (all different coils). This time at my local shop they found a bunch of rodent damage; tried to rewrap exposed wires, but too much damage and corrosion. They're waiting on new wire harness, but in the meantime it's running ok, but throwing a code because of the added resistance in the corroded wires (as it was explained to me).
So to summarize - coil failure is common (says my dealer) and check the condition of your wires.

covered that early on.
For my issue, I'm leaning to a leaky valve cover gasket ring around the plug hole. I've got about 170 miles on mine since I cleaned off the oil residue and it's running just fine.
I want to see if the residue comes back and creates the misfire again. that way I will know "FOR SURE" that was the issue

issue resolved
Issue happened to me on my 2010 ES 350, I bought the car used with high miles, and I figured eventually the spark plugs, coils, and major fuel induction service would have to be done, and sure enough $1,400 later the issue is resolved, when I heard the price I felt like I was going to faint, but the mechanic said all those parts were still original ( I hadn’t done any kind of tune up yet, and wasn’t planning on anytime soon)It is going to happen eventually on high mileage cars and in general, now my Lexus feels amazing again, the car has 122,230 and it drives and feels like it has 5 miles. So quiet and smooth, but it does guzzle gas, go figure the 2010 you can only use premium gas....Miss my CVT transmission my maxima had.

Maybe it is because my prior 2 cars had CVT transmissions, prior to the Lexus was a 2011 Maxima and that car had more HP, but to me it was better on gas due to having a transmission that never shifted, I averaged great mpg with the Maxima. I guess it’s just me, it has been 6 years since I’ve owned a car with a traditional 6 speed automatic. I’m still adjusting, it will be a year in April I’ve had the car, I have just been so used to the CVT transmissions, and have seen great mpg with both of my former cars, which is why I feel like my Lexus isn’t as great, and I need to fill this car up more often than I had to with my Maxima, and Subaru. I do love my Lexus though; great car.

I like numbers when it comes to comparing mpg, speed, performance, etc. I had a Maxima as well, and it too recommended premium gas. Back to numbers:
Fuel Consumption:
2011 Nissan Maxima (CVT): Premium Gasoline 22 combined city/highway MPG 19 city 26 highway 290HP GROSS WEIGHT 4698 lbs
2007 Lexus ES350 (6-sp AT): Premium Gasoline 22 combined city/highway MPG 19 city 27 highway 270HP GROSS WEIGHT 4679 lbs.
1/4 Mile:
2011 Maxima: 14.3 sec @ 97.7 mph
2007 ES350: 14.6 sec @ 99.0 mph
My nickel (no cents in circulation in Canada
) :
20HP+ on the Maxima vs ES350 may as well be a measuring error...
