You need fuel, spark & timing as the basics to start your motor. (there are other factors, but you need to look at the basic 3)
1.Check to see if you have fuel coming out of both injectors into the throttle body.
2. Check to see if you have spark. This is usually done with a spark tester
3. Once you have verified fuel & spark 100%, then you need to look at timing.
change distributor cap and rotor
When you replaced the plugs, did you check the compression? Did any of the plugs look different than the others? Low compression in one cylinder can cause misfiring. But then, so can a faulty distributor cap.
You don't. It has a D.I.S. ignition system and has no distributor or rotor. There are three coils mounted over spark plugs under coil pack cover (center top of motor) Each coil fires 2 pistons. They are not replaced as a tune up item. They are only replaced if faulty. Spark plugs should be replaced every 15,000 miles.

try checking youre timing
check and see if u have a hole in your muffler
this question best served in the automotive section
there is no distributor on a 98 rav. therefore no cap or rotor. replace the plugs and wires and the tuneup is done
If you have spark at all but one plug, the problem is with that plug, wire, cap or rotor.
try to get a new ignition rotor
I would recommend checking for codes before you do anything else.
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
