Can't believe I didn't think to check this. I just ran out and had a look with my multimeter, but all the ground straps were reading no resistance from one terminal to the other. Also checked between various points on the engine and body to the negative battery terminal, but found no problems.

There is that electrical corrosion gunk all around the positive battery terminal. I'm thinking of hitting that with baking soda+water, but please tell me if that's not a smart idea.

I got the Beck/Arnley sensors at $78 each.

I'll ask some people I know if any of them have a compression gauge. Last 4 tanks have been premium (but car can take 87) and we put Techron in the last tank and Seafoam in this tank. Again, also did the Seafoam Spray can at the throttle body but no effect. Some guy on the Lexus forum had the same issue and poured 4 cans of Gumout into 4 consecutive gas tanks and the light went out. I bought that stuff and we will do that going forward, but not driving it much because of all the problems so that could be a while.

Current Plan:
- Get access to a compression gauge
- Diagnose & fix the coolant leak in passenger compartment (probably heater core)
- Baking soda + water the positive battery terminal??

Thanks for help every1, please let me know if I'm missing anything.
