have the electricals checked. mostly the master switch.

look under car for adjustment in cable to rear-end.
could be time for a brake job.
lining worn down to point it needs to be replaced.

On most of your newer cars like yours the brake light switch is up next to the brake pedal. When the pedal is released, the switch is normally in the off position. It is a threaded switch to allow for adjustments and sometimes that is all that is wrong. I would check that first and if that is not the problem, the switch could be bad. Check it out before replacing it though. Good luck.

mixture or gas converter problem <replace gas switch or converter>

P0734 means that your transmission is slipping. This being the case, it is not surprising that the gas mileage is poor. You will need to have your transmission checked out professionally. Take it to a trustworthy transmission mechanic or to a dealer. Get a second opinion before you have any work done.

Sounds like a problem with your radiator. It gets too hot too fast. Get it checked to make sure that the fluid is pumping thru your engine correctly.

If the light is continuosly lit that indicates a fault in the SRS system have it checked by a shop you trust or the dealer

To the best of my knowledge the 1998 Hyundai Elantra has only a 1.8L (1796cc) engine. Are you sure on the 1.6L?

For the 1.8L:
Firing Order:
1-3-4-2
Cylinders:
(back of engine)
1-----2-----3-----4
(front of engine)
Ignition Connections:
(back)
o<---1
o<---4
o<---3
o<---2
(front)

As far as the markings on the outside of the engine, I'm not aware of any. However, by placing markings (white paint) on the Crankshaft Pulley (lip) and using the Timing Strobe you can get a relative idea. However this is not totally accurate, as the Camshaft Position is not visible. With a 4-Cylinder Timing symptoms will be very obvious.
Click on the following Link. It has the Timing Marking Diagrams for the inside of the engine.
