ok i had this light come on before i put my headers on, got a test done and they told me it was the o2's in the back but also said if i was going to put headers on wait and just get o2 sims ok, well last week i got my headers,y-pipe,o2 sims all put on and the guy told me the light should come off after about 80-150 miles that i have to give it time to reset well i have gone way more then that and its still on what should i do? and what does the light do anyways and is there anyway to reset it? thanks

 

You can disconnect the battery for a while and the light should go away. The light is just there to warn you that something is wrong.

 

it shoulda cleared if that was the problem. I would go to autozone or somewhere and have them scan your codes. Its free and youll know what the problem is. Im guessing you probably have a bad one in the front also.

 

ok went to autozone and said the code was po410 and something about secondary injection system, what does this mean, he said his computer was messed up but to take this code to a shop and they should be able to tell me

 

It means you need the rear 02s deleted and probaly need new front 02s.

 

When I ran Shell 93 octane its seemed to make it appear less often. What the hell just tune it.

 

ok where do the 02 sims come into place they put those in

where is a good place to get it tuned in arlington area

 

Have you done a pcm reset? Unplugging the battery will not do it.

The proper way to reset the PCM is key on, car OFF, pull the PCM IGN and PCM BATT fuse from the fuse blocks in the engine bay. Wait 10-15 mins. turn the key off, replace the fuses, start the car.

 

And nothing bad will happen to the car, right?
Just curious.

 

Right, it'll just clear the codes.

 

ok iam trying it right now

 

ok so far so good the light is off now i hope it stays off last time it came back on thanks

 

Any updates?

 

it came back on

 

AaronR is wrong about what that code means, it has nothing to do with your O2 sensors. The secondary air injection is talking about your air pump. If you put a cold air intake on the car or something and didn't hook the air pump line up it could be that, or if you deleted the air pump all together. A tune could fix that problem easily. Many people delete their EGR and AIR when the start modding their cars.

 

well all the guy did was the free mods,headers,ory,lid,cut-out could it have something to do with the free mods, and where can i get it tuned at in arlington are close by and about how much thanks!

 

Deleting the AIR is a free mod but it could be related to the lid if the air hose insn't connected to the lid, but as far as tuning, speedteck could do, They're by Fort Worth, and i think SQR or RPM is in Fort Worth as well, dont know their prices tho, you might wanna find there website and then give them a call

 

ok i know what it is now its the little pump that was connect to my stock lid, i have a g2 lid and there was no place to hook the hose up to it so i just took it under something and someone told me that it only has to do with the first 5 sec. the car starts up

 

and i know where the speedtek in dallas is (its where i bought my headers)

 

I knew it was prolly that hose, that's what i was talking about in that last post. But yeah it is pretty much only for the first few minutes of warm up, but it will make you engine light come on.
