New to the forum but I have been reading through relatable issues and don't think I've landed on one I can say is my exact situation.
I bought my car straight piped with the OEM downpipe, ofcourse got used to the noise and moved onto a catless downpipe (now full 3" piping) I immediately got multiple codes, long story short I cleared most by changing my spark plugs but I still have cylinder 1 & 3 misfire codes. I don't have my sensors in yet as I want to use an o2 spacer or something similar.
I also have a 3" resonator ready to be attached to help with the back pressure but not sure if I need it since the car may be in limp mode due to the missing o2 sensors??
Any thoughts or suggestions are welcome, my backup plan is to put the cat back on but I'd rather try the last 2 ways out first.
