well my cousin has a 2000 gt and installed a summit o/r h pipe and 1 chamber flos and its loud!!!!!!!!!!!!!!!!!!!!!!! the thing is that the first 2 o2 sensors are not connected and it idles like crap!!!and u can smell the fuel!!! what can i do??? i have a diablosport predator and turned off the last 2 o2 sensors and i thought i disconnected the first 2 and it works a little better but it stills idles like crap!!! any help????

 

personally, I'd get them hooked up. Why not?

 

Why are the front two disconnected? You need those for the PCM to determine fueling. Without them, it can only guess, and will run rich to keep the motor safe.

 

yeah man, big mistake, those are definately necassary, get them back on there

 

allright thanks

 

If I remember right I still used my mill eleminators to get the wires to reach them. I also think there are just wire extenders you can buy if that is the problem, where the wires will not reach.

 

no def dont use the MIL eliminators, they wont work if you use them.......just get the o2 sensor extendors and do it the right way once and get it over with

 

Woah! Definitely connect the front O2 sensors, and do not use Mil Eliminators, it is going to mess with the PCM's fuel map. Just extend the wires, or buy an wire extension set and you should be good to go.

Why would you think the O2 sensors wern't important?

 

I know you can turn off the mils with the diablo, but it is an off road pipe so they have to be turned off or will get check engine light. Am I right but are the first set of o2s just to see if cats are there or not.(mil) The second are the ones the count.(02) I already had the mil eliminators so used them to get the length. Then turned them off with the diablo. I guesse I did make that clear in the first post. But mil eliminators will work for the fisrt set if you do not have a tuner and just wanted to add o/r pipe.

 

no, its other way around, the 1st set(ones towards the front) are the ones that do the work. the second set(set furthest towards back of car) are the ones that check to see if the cats are working properly
