I had my exhaust Done and now my turck is running ruff

 

Did they damage the O2 sensor by chance?

 

No they didn't touch it. The truck had 2 cats they removed 1and the smoge line. Replacing cat with pipe new flowmaster

 

Was it running good before? What did they do with the air pump line? Just left it hanging and open to atmosphere, I hope.

 

Yes it was running fine before they did the exhaust. And no they Wielded the end closed. Someone told me that the computer may need to be reset.

 

Cut that tube open! Not only is the truck laboring to pump air out of something that's welded shut (if the belt's not smoking!) it's probably sending air to places it shouldn't be going. Open it up and let it hang. Do an air pump delete in the near future.

 

Oh, and computer doesn't know that the cat's missing and probably doesn't care.

 

I disconnected the air line but it still running ****ty. It iidols High in park and now it shifts hard at times. And if i stop at a red light it Stalls out
