I seek to know what is the problem with my E36 318i 98

At idle, the car turns not 100% perfect. At startup it turns 1000rpm and 750rpm tomb 8 seconds later .. it does not mount a 1500rpm down to 750rpm gradually towards (cold start).

when I give gas is cold (2-4 first minutes) the rpm down to 500 and hop it back, as if he took his bad air ..

I have a check engine code for the oxygen sensor was the catalyst.

can someone help me?

Sorry for my english ... :S
