You have a high compression ratio engine and it's recommended to use 91 octane. You can get away with the 89 octane, but the higher the better for the engine. Less chances of detonation (Engine Knock), Take note that it's best to keep faith full on servicing the Engine for Oil and filter changes. Good luck and keep me posted, be glad to help.

There is a knob beside the headlights under the hood, fairly good sized, looks like rubber and you can manually turn down your headlights. That happened to my 86 Supra last year and the sync was just off and once I turned them down they started working perfectly. Hope this helps

sounds like a vacuum leak, injectors clogged, bad plugs, plug wires or maybe low tranny fluid or combo one all, have it dynoed to save yourself some money of course.

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.

First of all, be certain that the leak is in fact from that seal. many leaks travel to that area.
To change the seal is fairly involved, you need to pull the trans and flywheel. There are some specialzed tools involved. Do you have manual or automatic? Manual requires clutch plate alignment on re assembly, by the way , if manual, be sure to change the release bearing and pilot bearing at minimum. Commonly it would make sense to change the clutch during this process....you're already all the way in there..
