So I recently ran into an issue when trying to get my car ready for emissions. The past few years I haven't needed to pass emissions so I ran catless longtubes. Now I need an emissions test so I installed some cats and loaded my emissions tune from Lund. The car feels like it runs well on the emissions tune but I'm seeing a number of codes (P0300, P0302, P0304, P0016). Sometimes this will trigger a check engine light, but not usually. The car doesn't feel like it's misfiring at all and my non emissions tune does not pop any codes. I've swapped plugs and coils to rule those out and it hasn't changed. Lund thinks it's odd but doesnt seem to know what is going on. I was about to just sell the car but I love it too much to just give up on it. I'm considering retuning with another company, I just need to pass emissions. I've tried crank relearn, didn't seem to help. I was down about 2 quarts of oil, added the difference and it took a little longer for the codes to return but not much. Anyone seen this before?
