Ok so I put the obx header on my car along with a aem intake and a magnaflow exhaust. Now after I got on it one day the ses light came on. Now this was the only time it ever came on and it was after I had installed everything on the car. So today I got in the car and found a person to smoke and what do you know itcame back on. Is there anything I can do to fix this. Now both o2 sensors have been replaced and the cat was removed and I am pretty sure the header is not leaking. Also in first gear the car seems to hesitate untill it gets warm. Please let me know if there is anything wlse I should try. By the way teh car is a 97 sunfire gt.

well that code pertains to a heated o2 sensor ineficcentcy...so you o2 sensors are whacked!!!! so to speak

You said you have not cat correct? That is why your light is on. You need to do a search for Manual O2 sim.

Anyways, I read the whole post and it shows 2 different types of anti-foulers. One is an 18mm and the other does not say. So do I have to buy both packages. I see that it says to install one right into the o2 bung is this the 18mm or the other one and then attach the other to the end but is that the 18mm or the other one and so all I need to do to the one on the end is drill it out to fit the end of the o2 sensor. Sounds like a good concept. Just need to make sure I buy the right parts

the problem is not the cat.
That hasn't shown up yet but will in the future.
The problem is the location of his #1 sensor.
Its too far away from the ports to get hot enough now, or its in only one cylinder's pipe and same problem.
Not enough heat = stuck at around .5v all the time., and this sensor does not have a built-in self heater to fix it.
sig not found
get a gm FACTORY one that will most likley fix your problem...i think anyone disagree,not too sure of myself as of this moment?

Ok I did not go and look up what this code was til now because of all the info going around. I got that it is this "Upstream heated O2 sensor circuit high voltage (bank 1 Sensor 1)" This is the first sensor that is in the manifold. Question what header do you have? Also did you have to extend the wires?
FU Tuning
Its the same problem my Pacesetter header has. Not sure of the code # but its slow response O2 sensor 1 bank 1 correct? It only comes up when the car is cold, has come on and off for the almost year its been on. I am inclined to believe protomec. Its what we get for buying a cheap header. Get used to it, i found lots of peps with this problem when mine came up.

x2, except for the cheap header part
Well, I am going to do that mod anyways. Also I did not do anything to the wires to exted them at all. I am almost positive that it is the sensor in the back because it has a code hso2 something like that. So I read a couple forums it is becuase you get rid of the cat. I have an obx header. So I will do the mod and it only cost like 5 bucks anywyas. So I will let you know if it fixes it, but it should if you read the other post.

Ok so I built the mech 02 simulator and it did not work. So If I build one for the first sensor that still wont do me any good if you are telling me that it is not getting enough heat. So what if I change the position of the sensors. Like to move the sensor from the back to the front and vise versa. Or put a heated sesor in the manifold, but this would require a couple more wires to hook up but should not be that hard. There has to be a solution. Please help me fiqure this out as I am pretty much a newbie, and you all are pros.

Regardless of what you think, it is not the second sensor. It is the first sensor. That code is for the primary sensor..
Also doing that sim on the first sensor will make it worse.

Thats probably true seeing that it wants more heat and making the sim on it would make it get less heat. So I guess that i need to find a way to get more heat to that sensor. Any suggestions? How hard would it be to make it a heated sensor? The sensor in the second postion is heated so if I just spliced into that to heat the first sensor to make it heated and then take the signal wire and leave that one alone would that not work. I think I might try that.

Bottom line -> you need a new sensor. I just checked service information and p1133 is for inactive switching, it has nothing to do with heat. You can add as much heat to the sensor as you want and you won't fix the problem. You must have bumped the sensor or its just old. Either way, try another sensor. That also explains your stumbling problem.
You need the first sensor, and you need to replace it. The second sensor can be killed, it only makes sure the cat is working. The first 02 sensor makes fuel adjustments and you NEED that one. If you have a problem with your second sensor fix it or sim it, if you have a problem with the first sensor you need to replace it. end of story.

x2... read the service info file I posted... it references the O2 sensor at the header (Sensor 1)
Ok it is the first sensor. He has already replace the O2 sensors per his first post. The problem is the heat. The O2 sensor requires heat to operate correctly. If the sensor is not at proper temp when the car switches to closed loop then it acts up. If you search on here you can find a post about putting in a heat O2 sensor off a grand prix. There is a kit that can be used on 95-99 J's that is pretty much plug and play (except for a ground).

OK, I dont know what to do. One of you are saying its the temp one is saying its the actual sensor. OK so first should I take the mech 02 sim off the #2 sensor or should I just leave it there. Will it cause me any problems. Second I will try and replacing that sensor with a new one, I think its lifetime so that wont be a hard fix and its possiable that I hit it during instalation but who knows. If that does not work does any body have the link to the mod to make the # 1 sensor heated. Thats all I can think of doing. Thanks guyes for your help
