Frogot about that!
The can't tell the gas mileage, the odometer works intermittetly (sp?). Anyway, the regulateo is good, as well as that vacuum lines running back there, plugs are newer, but old ones looked normal. The coolant sensor shows the engine at normal temperature (half way on the gauge) so I doubt thats the problem. I know that 240's sending units go out/work not 100% on these cars so I was wondering if thats the case. When I get my new cluster in (tomorrow) I'll check the sending unit like it says in the FSM. I'll check the O2 also. Thanks
