I have an SES light for random misfire and a P0135 code for something about "02 heater sensor" or something, I pulled the code up on auto tap. Does anyone know what this is? Also, when I have the codes pulled up on the computer screen, how do I reset the check light with auto tap?

you're probably going to need new O2's or it will keep setting the code. You won't lose performance or anything if you leave it go though. I throw PO133, PO135, PO153, and PO155 on a weekly basis. <img src="gr_grin.gif" border="0"> I just don't feel like replacing them yet. I've been throwing these codes ever since I've had longtubes.

BTW, to clear a code you click on the clear DTC's button. <img src="gr_stretch.gif" border="0">

So that mean the O2 sensors are bad? When I installed my headers, I got the sensors mixed up and might have accidently swapped them around, do the sensors need to go back to the same side (left or right, post cat, pre cat)? Or are they all the same? I have 2 extra ones from teh post cats which I don't need since I have no cats with simlators, should I replace them? And also, should that code be deleted when I get custom tuning?

hu, thats actualy kinda funny, I have the same thing. I freaked out thinkin somethign was wrong with the car utill i found out what codes they were.

I know when I put the hookers on I got a littel bit of anti sieze on the O2 where it shoudnt be. thought that might be it

I am thinking that the cause of my o2's going bad if that os what the P0135 code is could be my rich condition at WOT (.940) and also the backfiring on startup, might have burnt out the sensor <img src="images/icons/confused.gif" border="0">
