Headers on and got SES light

[Firehawk N Wv]

I got my heders puton and I had to run to the exhaust shope to get th y-pipe put on to haveit waelded and tohave them put some bolts on cuz Clar Image didnt supply them and on my way there with the open haders I got my SES light to come on and i dont know why cuz we hooded back up everything right except for the air pump tube the is leaking a bit so it needs tobe bent down a bit.So could anone tel me why im gtt th light.

probably the leak.. you meen egr right??

I wouldn't worry about it. After I put on my headers I got the light for about 3 days. After that it hasn't come on (about 2 and a half months now). Just wait and see if it goes off by itself.

I got the EGR tube fixed, so its nice and snug to the header. I still have the SES light though. It may be my o2's cuz my A/F gauge is actin wacky also. I also have a small leak on the passanger side so im goin to double check my studs.

It most definatley is the leak.

if you hit the 02 sensors to hard or something you might have ruined them...but check the leak first

If you were running an open ypipe then you didn't have a post cat O2 sensor. That would have triggered the SES.

I tightened up the studs and bolts on the header todya and it quiet down the leak a good bit.My SES light finally went off to. So it looks like it was the leak. I'm goin to triple check my studs again to make sure they are tight cu I know after they heat up you can snug them some more.
