Okay, so I went a BMW shop in Naples, I was there for 30mins….. they figured it out. I have two bad coils and the oil is to thin for the spirited driving. (Toyota service depart sucks)
Dude... they didn't even take my sparkplug out until Friday and I got my car back on Saturday. It took them two weeks to change the sparkplug. I have zero confidence on Toyota Techs with this car. What oil are you going to go with? I thought about liquid molly but haven't made up my mind yet.

The shop is doing some heavy research now. I will let you know,

It's what a lot of us use here in Chicago. It gets warm here, not hot hot. We only get in the 100s for a couple of months.
I'll give it a try. I tend to only drive the car at night or early morning in the summer. I want to say we average 110 in the summer. But I don't drive the car in the heat unless I have to.

Just put a new coil on No. 5 and NGK plugs. Car is amazing no hiccups no misfires
Looks like we had the same issue. I'm glad you were able to get it fixed. I was thinking of getting NGK plugs when they told me what the issue was.

16,000 miles no issues. I change my own oil and filters with Rotella T6 5w-40. Zero oil consumption. I have a catless dp with no tune, zero issues. I don’t trust any mechanic with my Supra, especially Toyota. Learn to diy, it’s so much cheaper.

From what i hear the toyota techs hate and really don’t give a damn about this car. They say it costs them time and money with no support from Toyota Bc they don’t know what to do either
