I do not know if this vehicle has a torque converter lockup or not, but sounds like it. Does the transmission stop shaking when you go over 65? Some vehicles have a torque converter lockup, which means when the vehicle is traveling at a certain speed in high gear the torque converter "locks" and there is no slippage to the transmission resulting in better fuel economy. if the torque converter doesn't "unlock" when you slow down to say 45 then the engine will "lug" causing vibration. If this is the case you are not hurting anything by driving, just shift to 3 when it shakes then upshift under lighter load, or take it to a shop that replaces transmission sensors.

the catalytic convertor not reaching operating temp , this may indicate that the o2 sensors are malfuntioning in some way , have the OBD codes read to narrow down the issue , i would try a fuel addative that cleans the catalytic convertor etc ,give it a good run at a highish speed if possible (50-100 miles ) as may just need the o2 sensors cleaning off of carbon deposits etc

Often the floor of the passenger side become wet if the drain pipe of the evaporator is: - Bent or twisted. - Clogged or, - There is any obstruction in its routing. The drain pipe is a rubber hose about 14 mm in diameter, located just under the evaporator (cooling coil) casing on the passenger side. The most easiest way to clean the pipe is to take it out, wash it from inside with water or to blow a compressed air slowly through its distal end while leaving it in place under the body. Note: Keep your eyes away while blowing the air. Hope that it works.

HI! I'm sure you mean 50 miles per hour as in speed and not gas consumption. Get it looked at by a mechanic.

The relay for radiator fan or the blower is stuck closed or shorted.

You may need to replace a tire sensor that is malfunctioning. Also check your spare tire as low pressure will also send a trouble code.

Could be just a problem with the wiring. Once had a client complain that every time he sat on passenger seat of his car the airbag warning light came on. Turned out it was one of the wires in that seat that was too short, and because he was big and always put the seat all the way back the wiring got stretched. But the best thing to do is connect a diagnostic machine to the car.

Warning Light for What? It is a vehicle, not human, it won't tell you when it decides to shut off

Really sounds like a battery connection. Try this,turn the headlights on, then try to start it,if they get dim,its a low battery,if they go OUT it's just a poor connection,most times it's just battery cables.

check the main fuse in the engine bay fuse box its a big one 80 amp this will have blown. doing this can also blow the ecu. but you may be lucky. horn going off is the alarm so this may have a problem to so would check this out as well.

i presume you are posting HONDA to a Toyota forum? how to, who can, what are specs. what is the question? what country? double posted too. the FSM covers this, and the rules vary by country. some are auto adjusting. (Europe)(complex rules) others have L/R -U'/D adjustment and others only up/down USA HL ADJUST. less photos from FSM .

1. Park the vehicle on a level surface.
2. Make sure the tire pressures are correct.
3. The driver or someone who weighs the same should sit in the driver's seat.
4. Clean the outer lens so that you can see the center of the headlights.
5. Park the vehicle in front of a wall or a screen.
6. Turn the low beams on.
7. Determine if the headlights are aimed properly.
8. Measure the vertical adjustment height of the headlights (A). The lights should reflect 2.1 in (52 mm.) below headlight height (B).
9. If necessary, open the hood and adjust the headlights by turning the vertical adjuster.
10. end
