I've been having this rough idle problem with my car for over a year now. I've spent thousands of dollars with my dealer trying to get it fixed, with no success. They've checked and replaced everything that could be associated with it. I had thought that the problem only occurred when it was damp and chilly outside, but I've noticed in the past week that it appears to happen when the wind is blowing. In addition, when the air cleaner is off and there is the slightest of breezes, the idle also gets erratic. If a strong enough breeze occurs, it can even stall the engine. Is this behavior normal? My dealer tells me that the have checked the intake manifold gasket and it isn't leaking. Should I believe them? Any other ideas?
