A year to date my car is back in the shop becuase I thought the same problem was happening with intake manifold. However, this time it is just the cylinder misfiring which could have been a result of the intake manifold cracking and water getting in the cylinder. I just read on this home page that an upgraded probe into engine fires of the 3.8l V6 is being done. This does not surprise me. This is a poorly designed engine and GM should be ashamed of themselves for putting out a product this poorly built. I foresee future problems to come and will be getting rid of my vehicle ASAP.
