Yesterday I installed my Jet Hot LT's and had a custom ORY made this morning, with a cutout on the I pipe. I deleted my AIR and EGR systems and put block off plates on the headers. I didnt even bother with 02 sims on the rear, and i made extensions for the front.

I am leaving my parking spot this morning and i put my AC on, start backing out, and my car falls on its face to about 500 rpm, then dies. I turned the AC off and started it up again, started fine and everything, put it just feels crappy. When I shifted to second I was barely gassing it at all in the parking lot of course and it bogged down again and died.

I went and got my codes scanned and I came out with P0140, P0160, and P0405 which are rear 02's and the EGR which I was expecting.

I also threw the P1153 code and P0153, which are both saying somethnig about the passenger side front 02 sensor i believe? I dont really know what these codes mean though can anyone help? Would one of the front 02's being dead cause my car to act like this? Am I gonig to F something up if i dont fix this like, today?

how did you make the o2 extensions? if you used the wire that comes in the kit and something like wire nuts thats your problem.

I would buy a set of O2 extensions. If you mess up the fresh air reference to the O2s, (by splicing and such) they will not function right. Not saying it CAN'T be done, but , well, it's just not worth the hassle to me.
(I've got the "splice kit" that came with my pacesetters sitting here on my desk, if that means anything)

Your custom extensions are likely the problem.

I have a 24" set of two that I just bought from TSP. They had ~300 miles on them and installed/worked perfectly. See the thread here: https://ls1tech.com/forums/lsx-parts-sale/381553-new-tsp-24-o2-extensions.html

Thanks for the responses, so the front 02 sensors can cause your car to hesitate like that at low rpms? It wanted to die down and even when i gave it some gas to keep it running nothing happened, like the gas pedal wasnt even working, then it just shot up to 1000. I just revved to like 2.5k out of first gear and it was fine, but at low RPMs it runs like ****!

Did you change the spark plugs when you did the header install? Could be a spark plug problem, you should check thema s well as the spark plug wires to make sure they are on correctly. If you did replace the plugs did you gap them correctly?

i used the kit that came with the pacesetters, and they are still working just fine after like 500 miles or so. i spliced them correctly then wrapped them completey in electrical tape and then zip tied wire loom over that, those bad boys are staying dry

i changed, the plugs, and they were gapped correctly.. i think. lol
Plus im not getting any codes having to do anything with spark plugs, just the 02 sensors. The best way to describe what happened was low-rpm hesitation, the gas didnt even do anything it was just dying. We ghetto rigged the 02's so i think ill just go buy a set of the corvette 02's and see if it clears up.

the P1153 is the heated O2 sensor Insufficient Switching- bank 2, sensor 1.
the PO153 is the heated O2 sensor Slow response- bank 2, sensor 1. hope this helps out a little bit

yea i looked the codes up, but i dont really know what that means...
I guess it means I need new 02 sensors... anyone know if I can get the corvette ones at dealerships or local auto shops so i can fix it tonight? thx - Darren
