It's a 3/5

 

On my last statement I meant to say "with the error code...". I would hope you didn't do the headers for good mileage. I just wanted to put out there that your mileage will falter even worse with the error code as the ECM is going to adjust fuel trims to cover for possible lean issue it can't see in the math because the heating elements are getting the sensor to "optimal" temp to make "optimal" readings.

Good luck with Dynatech helping you much on this topic. They have to play dumb or keep the customer service from knowing about it. otherwise they would need to warn you about it and then of course offer a solution. LOL

 

UPDATE Ok so I ordered my 2004 C5 rear O2 sensors. Reialized I needed adaptors so had some made for another $50. I drove to the shop where they were going to make them with O2 sensors not connected and It ran better than ever til the computer figured it out of course. Came home connected them and this morning ran like ****. It bogs at idle below 1000 RPMS. Feels like it wants to die. Also On the passenger side I'm confused. The front one is the one behind the wheel well or the one on the frame? Im confused where to connect it to now. Currently I have it connected to the one on the frame. Still have damn SES light on. So any ideas..???

 

they should be connected before the catalytic converters. Right before the LT collectors I would assume.

 

Just got off the phone with GM tech shop. I had them on right. So went back and changed them back. So back to the drawing board. Should I give it a few days to relearn it self?

 

Do I have to go back to the tuner for this? I was trying to avoid that trip.

 

I am curious if the mV in the original tune are the same as the ones that the vette 02's send back for the lean rich readings, I have no experience with swapping to different Narrow band sensors so I cannot give advice but it makes me curious none the less.

 

can you take a pic of where you installed the new sensors?

 

I can later. I have to run some errands. (Not in my truck) I'm a little fustrated to say the least. Not having a code reader sucks too.

 

Ok still haven't taken the pics. Busy weekend and now at my night job so.... Anways it still runs like CRAP. Actually died today when it was at idle at home. So idk. It performs ok when I'm driving. I changed the oil in it the night before last so I could driving it hard and aggresive too see if I can't shake "it" (SES light) off like a horse with a bad habit but no success. I did call the tuner. No answer of course. How hard is it to tune yourself if you buy the software? How much does that run?
