I recently got an o/r mid pipe now my service engine light is on. What do i need to get to fix this?i was thinking o2 simulators? and when my service engine light is on from this is it affecting my gas mileage?

 

Quick answer: No.

The CEL is obviously from the absence of the cats. You will need a set of 02 simulators or you can purchase a handheld tuner and have them turned off in the tune. I recommend that option because you can also bump up performance and play with a few other things with the handheld. SCT is the way to go

 

well i already have a diablo tuner. and i tried to turn off the o2's and the cel goes off for a while and its like the computers trying to still read them and comes back on later. maybe im not turning off the right thing? not sure

 

What code is it giving you (whats the actual number)

 

P0430 , and P1000

 

Ok, and you are sure that the handheld actually turned the rear 02s off? I know some SCTs have the option but wont let you do it without the aid of tuner software on the laptop

 

nah im not for sure i mean obviously it didnt work , so I dont know.

 

P0430, click here for more, is a bank 2 (driver's side) catalyitc converter efficiency code, P1000 (click here) indicates that the OBD2 system readiness tests are not complete. This is likely because the P0430 DTC was thrown before one of the drive cycle tests.

It sounds as though the tuner did not properly disable the monitoring of the cat efficiency.

You can make your own MIL eliminators for $5.00 or so...

 

I just did this last weekend it was kind of fun and didn't take to long no mil light since.
