Might have to try this little trick, putting spark plug anti foulers on my o2sensor to stop my cel from coming on due to the hi flow cat. Ill post pics if it works. Damn inspection time.

 

Btw.. Any clue wat size socket to get the sensor off?

 

7/8ths and good luck it never worked for me but I was catless

 

Thought so, yea im hopin itll work. I cNt turn the cel off with my tuner but it cones back on in 15 miles. Pkus in sure theres probably still gonna be something that shows up in their scanner even if i shut the light off

 

Everytime you clear the code you also reset the readiness test...it takes more than 15 miles to re-do the rediness for all pass!
I also doubt the anti foulers will work. What tuner do you have?
There is more than a hi flo cat at work there (judging by the posted pics of your rear bumper) she is hurtin in the fuelin department!

 

Great. Cuz when i turn the cel off, it comes right back in literally 15 miles. Never had a cel til i installed the dp last year. Ever since i installed it, i have the cel i keep turning off. Only thing more i have done besides the cat is the dp, res delete and super 44's(exhaust wise). But like i said, once installed the do is when the cel all started bc the cat

 

P.s. i just have my crappy suoerchips flashpaq. Car is on stock tune, i only use it to read and clear codes

 

Forgot to mention the cutout also haha

 

Just get it tuned off. There is an old thread about them with pictures.

So basically, install the anti fouler and bend the floor pan away from it...

 

bend the floorpan? no......get a tune to turn it off the CEL, dont waste time and money.

 

Wasnt plannin on bending anything lol, problem is i need the inspection asap, gotta ticket yesterday. Dont have the funds for a tune right now. Anti fouler might be worth a shot just for now

 

yeah, you can clear the code, but that doesn't disable it... not gonna work with that tool you have.. you need to get a custom tune done so the code can be DISABLED and then you'd be fine... need a diablo tool to get custom tuning done

 

Haha yup, i just talked to u the other day bout goin to you for my tune. Tax return and ur the first person on my mind haha. So i did the anti fouler install a little bit ago, could only fit 1 fouler on there bc the floor gets in the way of the o2 sensor with both foulers on. I turned my cel light off. DROve 23 miles to work so far no cel but we will see. If it pops back on im gonna have to figure a way to get that 2nd fouler to fit on. My inspection is passed due and i gotta ticket 2 days ago. So this needs to work or im SOL

 

I gotta drive at least 77 more miles without the cel poping up in order to pass my inspection sunday. Fingers crossed!!

 

You are not trying to do a trim re-learn to pass the Readiness test for your emissions.

You need to complete this:

A complete driving cycle should perform diagnostics on all systems. A complete driving cycle can be done in under fifteen minutes.

To perform an OBDII Driving cycle do the following:
•Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.

2.Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.

3.Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.

4.Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.

5.Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

6.Accelerate. Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.

7.Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.

8.Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

Ill have to try that tonight when i leave work

 

Does all that need to be done immediatly step after step? Bc im all highway driving gonna be hard to slow down to 20 mph

 

Guy at the shop is the one who told me to drive at least 100 mules with cel off or ill fail..

 

Ive driven 45 miles so far since putting the non foulers on...so far no cel. I think it might actually work lol
