car isnt running hot.kills battery unless disconnected

car would sit for 3 or 4 days nad we would have to boost to start. Eventaully the battery would only hold a 11 volt charge and then evry time we tried to start it we would have boost it. I replaced the battery and the car sit for 3 days and then no power. I also changed the battery cables.

the dioagnostics code reads P0340 and P0430.. so what should i do first and look for? everything looks brand new on this car... i just bought it but the ckeck engine light wont go out...the car passedd emmisions but the light wont go out..even f i reset it..

how much should it cost

We replaced the lower compression hose and soon after we had the leak. It has gotten worse i can see leaking even when the car is in motion. it is like the car is peeing but only under the passenger side headlight.

97 Merury Sable 6 cyl DOHC just started showing service engine light and local Autozone read P0171, P0174, P0402, and P1401. Just replaced EGR valve, sensor, solenoid 3 yrs ago. If MAF goes (171/174), can it cause the EGR codes (402,1401) as downstream impact?

Do i need to remove the exhaust that is blocking the pan from coming out or the motor mounts?

How do you remove the left side trim to get to the instrument panel

Which catalytic converter is normally on the 97 sable??? is it direct or from right or from left???? makes a difference in price range

Can not get heat inside the car. Theomstat is working, not overheating. Can it be the water pump? Or maybe the heater core.

I recently bought a used Sable and when the car has not been on for a few hours such as 6 or more hours the radio won't turn on, however if i pop the hood in the front and slam it shut the radio will work. But this is only if it isn't on for more than 6 hours because i have left it for an hour or so and the radio turned on. Does anyone have any clue what could be the problem?
