I recent changed my bank 2 sensor 1 to try and solve my rough idle. After the replacement it seemed fine and then the next day when I started it it had a rough idle worse then how it was before. After a couple days it went away but not it’s back as well as it’s idling rough even when car is warm now I have codes p0132, p0152 , p0138 and p0158. Thanks in advance
edit: car also struggles to accelerate

 

Replace the other side and see if that helps. Usually try to replace things like that in pairs since the other side is usually close behind.

 

someone had told me it’s the intake manifold gasket but I’m not sure how I could test it

 

Did you recently do work on your intake manifold? That's the only way they get damaged.

 

The car is running too rich (high voltage) and you will have to monitor the voltage or get a better scan tool to see what is really going on. What year is your coupe? The older gen cars are narrow band 0-1v and the newer cars are v4.2 wideband 0-5v. If you use Torque pro and a bluetooth OBD2 adapter you can monitor O2 voltage per side. On the wideband cars it should be about 2.1v - 2.2v at idle warmed up.

If you think you have a intake / hose leak the best way to find them is to build a smoke tester. I built one years back out of a paint can, air compressor fittings, pressure regulator, rubber hose, and throw about 10 sticks of incense from the dollar store into it. It has found leaks in 10 minutes that I would have spent days looking for.

 

my cars narrowband and I think I’ll just end up making a smoke machine at this point

 

when I first purchased car about a two months ago it always had kinda a weird idle so the previous owner could’ve done some work in there
