Honda Prelude high idle?

i drive a 1990 honda prelude, it has a 2.0 fuel injected engine and it idles high.

when you start the car is idles at 1100 Rpms and idles rough
when its warm the car idles at 1500 - 2100 rpms

after the car has been running for a while you can smell a strong gas smell

i have tried many adjustments but nothing seems to help, plugs and wires are both new

would a bad O2 sensor cause these problems?
