The issue that I am having is when my car idles for a while (or drives) the engine will stay in open loop, and when it changes to closed, loop it either goes too lean or rich and stalls out. I'm thinking it is going rich because I cannot restart the engine after it dies. (Flooded?), but if I let it set for an hour or two, it starts right up and idles great. So I replaced my O2 sensor with a denso....still did it. My vacuum is at ~18hg at idle and it boost to 10psi (where I have it set). I know I don't have and vac/boost leaks so the next thing I looked for was an exhaust leak around the O2 housing. I made sure the O2 housing was tight to the turbo, I have a 3 layer metal gasket there. The only thing I saw was the gasket between the O2 housing and the downpipe looked like it may have had a small leak. I bought and extremepsi 6 layer gasket and installed it. Is there anyway to seal that up any better?
