need help
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
