Can splicing in wire to extend the length of the o2 wire since it's too short for the coupling to connect cause false readings? Someone mentioned it today, and ever since I installed the headers I've been splicing in wire because my o2 bung is farther back so they don't reach. I can't imagine it doing that, but I'm just too tired and stupid today from lack of sleep last night.

put the new (expensive this time) o2 in last night and already got a code 13 this morning. It was in closed loop for the most part I think.

 

Or maybe like I mentioned in the pacesetter post. The pacesetter pipe moved it too far back and now it doesn't stay hot enough.

Course, why would I be the only one with that problem? I'm going to bed.

 

As long as you soldered the connection, you should have no problems. If you used crimp connections, yes, that will cause a problem. When you're only talking 0.450 average voltage, if you have any kind of resistance in there, it'll give you false readings (low voltage).

 

how much farther away from the stock location did the y pipe move the 02,if it did infact move it far enough back it may not be reaching proper operating temps a 3 wire heated o2 would fix ur problem

 

I would guess about 8 inches to a foot. I'll be going out in just a bit to see if I can get the upper wire section to reach down closer so I'll get a measurement.

edit* Nevermind, the 'Y' on these headers is longer than the Y on the old pipes. The o2 is just around the bend from it. It's only a couple inches farther from the Y than the old one.

The image in my head from when I last looked at it made me think it was farther.

On to getting the coupling to reach I guess.

 

Pulled the o2 and pulled wires out of splice crimps. Tried to solder back together, but it wouldn't stick at all, so I gave in and crimped them together hella tight.

After much pulling and moving stuff around I got just enough slack in the wiring harness to get the plugs to reach. It's basically a stretch between the ICM plugin and the o2 plug. A few zip-ties keep the o2 wire off the exhaust pipe and the wiring harness from moving too much. I'll have to check it again tomorrow to see if things have moved around at all.

I'll also test the open/closed loop status when I get to work and it's plenty warmed up.
