everything works with the key in the on position, but when it is in the off,nothing works.

but not all the time and it back fires if i hold the gas down but will get going if i pump the gas to get up to speed....any idea what this could be?

where is the thurmaste at on my car

Is there a perminant fix for the failure of these parts, or is this just something I have to live with as long as I own this car I have replaceed all of these parts at least twice in the last year.

it idles good it just sound rough

Sometimes when I go out to start my vehicle in the morning the overdrive will be The overdrive turns on and I don't understand why it turns on.

The oil filler cap has a whitish sludge on it and the is smell of fuel coming from coolant hose fill cap- as I fill coolant, it runs out of exhaust pipe and muffler. Truck ran little rough originally when it started overheating but it overheated other day and won't start back up along with the list of problems I prior stated. What is cause? Is it head gasket or something else or is it a couple things?

and it stalls if i burp the gas

Also, is it dangerous for the engine to drive around with this code? How much is it to fix/replace it?

Checked again with computer and computer still says need new cap could there be something else causing this?
