Recently I have been putting my car back to stock. I had an intake and testpipes. I replaced them back to originals and then got a P1273 two days ago. I rechecked everything and made sure everything was tightened, then reset the code. Well this morning I got the code again.

Is something leaking or does the ECU take time to clear out all the codes? I've searched and people getting this code are FI. I only had an intake and testpipes...

Any suggestions?

 

From what I've seen on searching, that deals with your air/fuel ratio...try cleaning the MAF sensor maybe?

 

Alright, i will do. Thanks for the advice!
