I put on a set of LG off road longtubes a few weeks ago and all went well until last weekend. My engine light came on and is throwing a p0133 and p0153 code. I know this means h02s slow response but what do I do to fix it? I have new 02 sims installed and like I said it worked great for a few weeks.
Hey Frank, thanks for the advise. I will check to see if there hooked up backwards. If that's the case, I wonder, would they work for a week then throw a code? How do you tell if they are hooked correctly?
Thanks,

you know what, scratch my suggestion about having the O2's hooked up wrong, you would know it most likely right away, I had this problem and it caused the car to misfire.
I think you have a bad 02 sim or something along that line.
