Hello i recently installed an slp catted x pipe onto my mustang that’s paired with an slp loudmouth exhaust system and it wasn’t really loud to my liking so i decided to remove the cats and replace them with a piece of straight pipe. my car ran fine for about a week until i turned it on a few days ago and got a check engine light. I headed over to autozone and used their code reader to get a diagnosis. The code read Intake manifold gasket as the most likely issue and also system too lean bank 2. So i replaced the intake gasket and torqued everything back down to spec. i also replaced my rear right 02 sensor since one of the employees said that my rear right 02 was bad and cause i’m not so familiar with that code. My check engine light went away until the next day i received it again, same likely issue! my car wants to turn off at idle and i don’t know if it’s because i removed my cats. Will a tune help with this issue? this is my daily car for now and i’d like to get it fixed thank you
What makes this problem better or worse?
car runs and turns on it just idles poorly and my fuel mileage is terrible!! i ran through a full tank in 3 days
