Yes, agree with the others ^^^^^^^ : Codes please.
Also:
How many miles on it?
How long have you owned it?
What region does it live in?
Has it suffered any major trauma recently?
Did the speedometer stop working immediately after changing the oxygen sensor? . . . or were you able to drive for a bit and then it failed?

Need to scan all modules NOT just the PCM which is what most code readers do.
