P0133 & P0153 codes after header install
After installing my LG stainless steel street headers, I keep throwing these codes for the 02 sensor heaters and of course it is turning on the check engine light. Does anyone else have this problem when installing headers? How do I get the light to stay off? I talked with LG and they mentioned something about newer vettes having hotter heaters in the 02 sensors after 01, but my car is an 02, so I am not sure how to tackle this issue.
Thanks,

2 choices.get a set of new front o2's or use the adapters and move your rears up front.i have the older lg pro system[only uses 2 sensors,no rears]and moved my rear 02's up to the front.no problems in 2 years. your faults are for slow response.i don't know how many miles are on your o2's,but if you get new fronts your problem will most likely go away.

My system is using just two O2 sensors, the rears were turned off during the dyno tune, the rears have been put in as the front sensors as they apparently have less tendency towards this problem. My sensors have 30k on them right now.

I pulled the O2 sensors out this afternoon and cleaned them with carb cleaner and blew them out with compressed air, this is what LG suggested, and I still got both codes thrown on the drive home, does anyone have any suggestions for this before I drop a couple hundred bucks on O2 sensors that still might not fix the problem?

1153 code
Have almost the same problem since installing Dynatech Supermax headers, cats, and x-pipe. Code 1153, insufficient switching, right side,rear. I bouight 02 simulators and install them .cleared code and the second cycle, got 1153. Car runs like a scalled dog, no complaints there. Hate seeing ch eng light. Will probably LS1 Edit out the 02 sensors. Unless somebody has the answer. I would rather do it right.

i don't get that one either.carb cleaner is a hydrocarbon just like gasoline.raw fuel will kill a o2 sensor.plus slow switching is because of the heaters.if the o2 fuse under the hood is not b lown,the heaters in the o2's are worn out.it is common for the heaters to tank over time.when you add headers the faster exhaust flow doesn't allow enough heat on the sensor[the stock system retained enough heat at the sensors to compensate for the worn heaters]

your fault is for the FRONT sensor on bank 2[right]not th rear.you need a front o2.that's why simms didn't help your problem.same thing as chris' problem.the heater is worn out.

From looking at my car, it appears they use the factory rear O2 sensors as the "front" O2 sensors for the headers, should I order sensors for a 2002 model year, or did they upgrade the sensors for 03 or 04?
Thanks again,

order 2 rear o2's for a 02/03,04 is a completely different plug.rear o2 heaters have a higher wattage heater

I'm having the same issues after headers. I'm told the 1153 codes and others can be "edited" out to eliminate the "Check Eng" light. Any rich/lean issues caused by this? I
