hey Guys .
so I m dealing with this code
a bit of history : after working on the top of the engine looking for Coolant temperature sensor in the wrong place !!
mistakenly removing stuff such as intake hoses , intake manifold I know ! seen a video where I thought the sensor was located turns out to be underneath , placed everything back together good and tight I though ! after driving few days getting this code now .
so I m thinking I got a vacuum leak .. this morning did a smoke test I can NOT see any smoke except over OUT of the air cleaner box questions
is that to be expected smoke out of the air cleaner box ?
should I consider the 02 sensors ?
what else should I be looking at ?
