O2 Sensor
I have my after cat o2 removed and my engine light goes on but the fuel efficiency hasn't changed. Is the other sensor doing the job? do i need to replace it or get an emulator??

The before cat 02 sensor is used to monitor A/F ratio. The majority of experts out there say that the after cat 02 is there just to monitor wether the Cat is working properly or not. There are a few that believe the 2nd 02 does effect A/F in some part throttle cruising conditions, but I have never heard of anyone having an A/F problem with the rear 02 disconnected.
Curious to know why you removed the after cat 02? It's unclear by your post if you removed the cat itself. If you want to leave it out and clear the SES...99 GTP has your answer.

Re: O2 Sensor
Well I removed it because it was broken when I removed my u-bent. The only thing that worries me is that I might not pass the aircare with no o2 and the camshafts I'm gonna get. Will the simulator help me pass it?

Don't know about Canada, but I've heard that in states that require a smog test an SES light is an automatic failure. As far as cams...the ClubGP board has several stories of people passing even with radical cams, but also have stories of people failing with mild cams. Not what you want to hear, but it looks like it just depends...
