I plan on checking the plugs this weekend for oil and the antifreeze too.

Any thing else I should look into?
Check the vacuum hose at the intake coming from the Vacuum Modulator for signs of fluid. Mine was leaking and burning trans. fluid through the engine. I replaced the VM about 3 years ago and no problems since.
