Short back story...
I just put in pacesetter LTs, ory, and O2 sims. Now, I am getting a p140 and p160(no avtivity from O2 sensors, bank 1 & 2, sensor 2). Basically, I think my sims are not working.

One thing I noticed is my fuel mileage over the weekend was shitty. With the codes its throwing, am I in the lower octane table? Thats the only thing that I can think of for the fuel consumption.

Any help is apprciated.

**EDIT** I just ordered a wait4me tune.

 

You are running rich.. a little tuning will put you back where you need to be..

 

I believe you, but wouldn't logic tell you that by icreasing airflow (LT's) you would lean out a little bit.

I just ordered the tune from w4m...

 

no, 02's are seeing more air thus telling the pcm to dump more fuel..

 

STUPID LOGIC

 

so you put the simulators on the front are the back o2.it sounds like you put them on the front if so that is your problem.

 

i guess i should read the whole post.. that would be definitely be the reason..

 

The codes are p140 and p160...Banks 1&2, sensor 2 (left and right sides, rear sensors).

no the sims are definitelty on the rear. That would just be silly. I think the problem is that the sims aren't putting out the right ohms range for the truck. The guy at thunderracing (can I say that?) said they might be the wrong ones, but as they ar ethe only ones left selling sims (they have been discontinued), I bought em and hoped. Oh well. Tunes on its way

Hey, next week i'll have some sims and 2 24" exstentions(which are not being used for sale
