Help, engine light wont go away

[RedBullitt]

help, any advice would be appreciated. i have an 01 gt with bassani high flow cat x and a bassani cat back. A few days after the install of the x, my check engine light keeps coming on. Will mil eliminators solve my problem? how are they installed and do they have any negative affects on performance?

Well, It sounds like something isn't agreeing with your x-pipe. You can go to any AutoZone and they will scan your codes for FREE. That will tell you exactly what it is. If it does turn out to be your O2's you can buy some or make some for cheap. They have no adverse affect on performance. They just make that irritating light go away.

Yes you need a set of those MIL's

Some of the high flow cats on the market are not efficient enough at lowering emmisions to satisfy the OBDII checks of your PCM. You will need to run MIL elininators Or get a chip or programmer that can shut off the rear O2's

aight, i got my codes read and it is pulling a p0153, o2 circuit/sensor slow response bank 2 sensor 1. any ideas? just got a diablosport predator, can that help me out any?

 

[smokin 04]

That code is for your upstream O2 sensor so MIL's wont do any good. There is a possibility that your code is a coincidince. I work at a Ford Dealer and usually when I run across that code it ends up being the O2 sensor is failing. You should check for any leaks around that O2 sensor or where the X-pipe meets the exhaust manifold. any leaks can cause a false lean reading from the O2 sensor.

 

[RedBullitt]

is that code for the drivers side or passenger side where it connects to the manifold?

Bank 2 is the passenger side.

 

[RedBullitt]

thanks

no, bank 2 is drivers side. bank 1 is the location containing cylinder 1 (on the pass. side)

Bank 2 is driver's side. I have the exact same code on my car with the same exhaust setup. I couldn't find any way to turn it off so I had to turn that code off in the computer. Bank 2 on mine has a high long term fuel trim...I think it was around 6% or 8% while bank 1 was lower. I'll send you an email that I got from Bassani when I asked them about it if you'd like. Let me know. If you ever find out anything, please tell me so I can find another way to fix it...its also affecting my gas mileage really bad.
