I have a 01 ta w/lid,cold air,slp mass air,slp lt's,3"y w/cats,slp loud mouth cat back. I dont know if its tuned or not. But on a full tank it gets 160 miles. The code it shows is "air injector pump relay a malfunction" it did show a heated o2 sensor bank 2 sensor 1 but it went away. Any ideas?

 

So your engine light is on??

 

Replace your o2s!

 

Get AC delco o2 if u can, bosch give me problem. btw does your blow a little smoke ?

 

I used everykind of o2 and they all failed. The big fix was a proper tune for me in the long run

 

Same here I tried diff O2's with no luck until I got mine tuned.

 

+1 for the tune. My car ended up being tuned for the wrong gears when I bought it. I was kinda pissed. Ran a hell of a lot better when I got it tuned right though. And boosted fuel economy by a lot!

 

thanks for the insight guys
