when I installed my jet hots I removed the o2s it's a 1996.Should I have left them? I also removed cats and air pump. will this make the car run lean? low power?
p.s. how do I use spell check on this forum? thanks

 

Which O2s did you take out? Hopefully not fronts...
For back ones, you'll need o2 simms in place of them.

Air pump might throw codes but can be programmed out.

BTW, you'll need the front O2s to keep your car from losing it's mind when it goes closed loop. The back ones just monitor the performance of the cats. No cats=ses w/out o2 simms.

 

Gotta have front O2s.

I don't think there is a spell checker. Have you seen the way people spell around here?

 

Shoebox is right about the front o2's. But, you don't have to have the back ones. It will throw a SES light but you can buy rear o2 sims or just have them programed out. All the rear o2's do is check to make sure the cats are working properly.

oops I removed all o2s but did have computer reprogrammed to remove air pump and I guess rear o2s maybe that is why SES light is on! Thanks for the input.
