My long terms are good they go to 0 at wot but after a sec this one jumps to 14.62.Why ?

 

what FTC are you in when it jumps to 14.62?

Dave

 

It happens when I go past 3/4 throttle.
Also what O2 sensor is LT bank 2

 

We did our own splicing of wires to extend the passenger side O2 hook up.i wonder if the computer is reading to much resistance or something.We were very careful in cutting and soldering and shrink tubing.We did use the same gage wire.I also did use some foil tape to protect even further the wires.
Hmmmm

 

do you know what fuel trim cell you are in? im wondering if its the particular FTC or just the o2.

Dave Im not sure????
Im going to switch the passengers side post O2 sensor with the pre O2 sensor passenger and see if its the O2 sensor.

 

dave all i did was install headers,before things were good.no ses light at all.

 

well im assuming since you know your LTFTs you are logging some how right? If so, you can check what fuel trim cell you are in.

Dave

 

I only have a predator.

 

Well I just went out and cleaned the 2 passenger side O2's.They both had a little black soot on them.Then I switched them front to back.
No more funny numbers on bank 2.They all go to zero at WOT.
Now time to set my enrichment and go from thier.
Thanks for your input.
Hope this clears things up.
