What are the engine RPM's doing

The P/windows will have relays in the box under the hood. Instruments should be 15 amp fuse in panel inside the car under the dash. I strongly recommend a Chilton manual for this car.. It is very complicated.....

Toyota has removable tubes that are sealed by O-rings. I believe you have to remove valve cover to gain access

I think you have a bad head gasket too. It's leaking coolant into the combustion chamber. If you pull out your spark plugs one at a time you will find one plug that is very clean. That's because when the coolant vaporizes, it gets the combustion chamber very hot, thus cleaning the plug.

You must replace the head gasket. I would think you could get it done for $1000.00 at an independant shop. Call around to several shops to get estimates.

Might be clogged fuel line

check fuel injectors or throttle position sensor

probably a floater gauge. after a long time they will get gunky from the gas and get stuck. easiest just to get a new one
