p0430 code issue

[emsrescue41]

I have headers with high flow cats and x pipe and keep getting the code. Car does have a bama tune with just a few small things. I have inspection coming soon and they connect to my port for that. How can I make the code go away for good? I have been running the p89 tune and just switched to the s87 tune to see if it will go away but have to wait for all the cycles to tell.

most likely it's a tune issue

are you clearing the DTC and it's returning?

 

[emsrescue41]

yes and have all new tune up including new o2 sensors when I did exhaust install.

 

[stkjock]

it's "tune" or "calibration" not "tune up"

yet, you still get this error after the new tune, was the tune updated? or you just loaded a different tune?

Search and you'll get the answer... hint: spark plug anti-foulers.
A tune won't help, unless the count limits for rear sensor counts are increased to max limits.

I guess on the sensor to pull it out of the flow?

The sensor is detecting not enough flow difference between the front and rear sensors. This is because of your high flow cats. 02 Anti Foulers will usually solve this issue. Make sure your cats aren't blown out as well while your installing the anti foulers.

Just a heads up, the O2 anti foulers are just spark plug anti foulers from Dorman. They cost about $6-10 a pair, so save your self $40 and pick those up instead.

We modify these to better fit the Ford 02 monitors, otherwise its a tight fit and can cause problems.

Ok made my own antifoulers and p430 is gone....... but now I can't get p1000 to go away. I have 100 + miles since reset.

Always seems like it takes a few days to get the OBD ready on everything. I bet it's your evaporative system check that is holding it up. That was always the last one to get cleared for some reason. You can try doing the Ford Drive Cycle to insure you hit all the parameters necessary. I think its the long coasting with no throttle from 50 or something like that that will trigger the evaporative system to trigger, but I'm not positive. All I know is that it's always the last one to clear for me. Usually take 3-4 days for me.
