Sorry to hear your getting problems again, the only suggestion I can make is to call Adam. Maybe my car will be ready and I can get a ride again :blink: .

 

I think those are the rare "Modification Overload" codes Don. :laugh:

 

bad gas??? or 02 sensors are wearing out.

 

I had the same problem. Since the banks are further away from the engine with LTs it was taking too long for them to warm up and going into open loop before they could warm up properly. My tuner extended the loop time and I havent had a problem since. Funny thing is it ran ok for a while with the LTs and then one day kapoot. Hope this helps

 

i got the p0153 onced since the lt's, ken at MD told me the same thing he would have to change the tune a bit

he said it's a common code to get with LT's

 

I just talked to Adam and he said he adjusted the tune to compensate for the new O2 placement in the headers.

Since this has been happening on and off for a couple weeks, I'm not sure if "bad gas" could be it. I've been through a couple tanks, and I also ran 10 gallons of race gas through the car last weekend. But it happened before and after that.

I may stop by a Ford dealer this afternoon and pick up two new sensors just to try them out. Anyone have an idea what they cost?

I bought some plug & play 02 sensors from Orielly auto parts I think they were 44 bucks. The ford dealer wanted 100+ I'll post the Orielly/ bosch part number when I get home

 

I've bought the OEM one's at the dealership for $67.

 

I paid 49.99 for this replacement. It has the correct connector

 

I have a bad 02 sensor as well but I haven't thrown any codes. I just have to let the car idle for 90 seconds befoer I start driving. Adam is got me a new one under warranty from his buddy at the dealer maybe he can do the same for you.

But I would wonder if it happened after you used your cut-outs? I never thought of it before, but that might cause issues with your sensor when you open them??:blink:

 

Thanks, Roy!!

Mark, I've thought about that, but the cutouts are quite a ways behind the O2 sensors. And it only throws the code when the cutouts are closed.

 

28 posts but still no love..

 

Sounds like a job for lostsoul...

 

Have you tried taking them off and looking at them? If so I would try the new sensors (Bosch)...chances are the new engine and supercharger are going to cause the same thing eventually if you get OEM sensors. I think since the AF ratio is richer than what it is supposed (12.8 for stock N/A and mid-to-high 11s for S/C) be it's fouling them up faster.

 

 

Don doesn' have L/t's.

Don - yeah, you'd think it would throw the codes when they were open but I would still ask around about it. Perhaps after closing, the sudden change is setting them off? The only thing is you are the ONLY one I know with cutouts so I don't know where to ask...:blink:

Actually, I've had LTs longer than I've had the blower...

And it's doesn't seem to be happening relative to opening or closing the cutouts. It threw both codes this morning driving to work, but I never touched the cutouts.

I'm going to watch it for another day or two, and then probably replace the O2 sensors this weekend. Process of elimination I guess.

oops! I could have sworn you had the shorties...lol I was so caught up with the jet coating, I guessed I missed it...:blink: Good luck - probably just need new sensor.
