Oil light goes on and off as i speed up and slow down in my hyundia tiburon

check to see if you have a viscous fan hub on the fan if so have it replaced as it is failing . From your description of the problem when the vehicle slows down there is a drop of air flow through the radiator which results in the temperature going up and as you speed up the air flow increases and cools the radiator down

Chances are the dome light is grouped into a circuit for other lights as well. You should have a "meter" or "head" listing in the fuse box. One of these should do it. The fuse box should be under a kick panel below the steering wheel on the left side.

Check the level of oil with engine off and after it sits for a hour.

Most likely low engine oil level , check and fill to proper level. If level is good, then the level sensor is failing.

They are designed to change as the motor changes speed. If you have 80 lbs. of oil pressure than you have very good oil pressure in your engine. If it gets higher than 80, I would talk to service dept. at your local dealer.

check if it has a crankshaft position sensor if it has test it-

Your electrical lines are grounded. Have it checked by an automotive electrician

I'm assuming it's a 5 speed standard trans? If so, you could attempt it, but you'd need a lot of technical data before you try. Go to http://www.hmaservice.com/ and register your vehicle. After that, you'll have access to manuals, service bulletins, wiring diagrams, etc.
