I got a P0155 code after getting the Solo Performance high flow cats and a set of downstream O2 sensors from American Muscle installed yesterday. I cleared the code and it didn’t come back on for the remainder of the ride. I let the car sit for a few hours and the code came back on after crank.
I had no codes prior. I wont be able to take my car back to the shop that installed it until Monday, but I’ve googled everything on the code and couldn’t find a clear solution for my specific situation and car.
Is it because I didn’t get the upstream O2 sensors replaced as well? Something simple like a blown fuse? Would an adjustment to my tune from MPT solve the issue? I read that riding with that issue can cause major issues in the future so I want to get the issue fixed ASAP. Any advice would be much appreciated. Thank you.
