Just installed the Espelir DP and Invidia TP, there is no o2 bung on the TP, didnt plug it back and went out for a quick drive, guess what, no CEL, am I expect to see it after a few hundred miles?

 

Possible

 

It will throw a code within 100 miles

 

+1, it just takes a little bit of time

 

Couple of WOTs and it'll be on in no time

 

Mine took an hour to throw the code. Went to Autozone the next day, bought 2 anti-foulers for around $4 and it was fixed

 

go to pepboys in there"help" section and buy 2 antifoulers and drill out the hole for one and then screw it into the other one and plug into test pipe. 2k and no problems sofar.

 

Yup, the light just came on an hour ago (80 miles), going to get the mechanical 02 fix, see if that would help.

 

Mine did the same, lasted about 50-60 miles then wham its on.. :[

 

just to clarify, you have to put your sensor back into your exhaust stream somehow. You can't just buy two anti-foulers and leave the 02 sensor dangling. You posted you don't have an 02 bung on the pipe, so you'll need one of those also
