The Plot Thickens...What Is This?

Would spark plug tubes cause the 1128, 1130 codes? I can certainly see how it would cause the idle issue at startup. I also suspected a motor mount change might be in order.

I had those two codes in the past, did the usual suspects, maf cleaning, etc... and I also had oil seeping in those same places. I did plugs and tubes, and it solved the oil seeping, and also the codes haven't come back. I don't know if it is related. If oil could seep out, could air leak in? Does that even make sense. I also did several other repairs at the same time, new fuel filter and new passenger side post cat o2 sensor, so it may have been one of those other things...

A misfire due to oil in the sparkplugs can cause a misfire code.

Check the bellows tube on the bottom of the AOS.

Another vote for spark plug tubes. Easy DIY fix.
