Thank you, I might take the upper intake manifold off entirely just to check for cracks causing excess air into the engine. The thing that confuses me is, I'm getting terrible gas mileage, 10 - 12 miles per gallon and I'm driving her extremely gentle. if it's running lean why the terrible mileage?

I also checked my transmission fluid and it is brown and burnt smelling, I'm concerned it's also a transmission problem.
