battery terminal problems can be handled with simple steps Firstly remove both terminals and clean posts with sand paper. clean inside terminals until shiny metal.

Where to begin.Any chance you can take the truck back for a refund ??If not, you have some major expenses ahead.If the oil is in the cylinders, the odds are you have rings and valve guide wear which would require rebuilding the engine. Replacing the valve cover gaskets would only be a concern if the oil is on the outside of the spark plugs. Fixing one thing such as rings or valves with that many miles on the truck would not be realistic.The bearings and oil pump and so on would have 192k on them.The timing belt and water pump should be replaced every 75,000 miles, so you should be on the third one now and another due at 210k.The big issue is the mileage on the truck. Replacing or rebuilding the engine now would be a big investment on a truck that is close to the end of life regarding the rest of the components such as suspension and transmission. The 3.0 engine and drive train have a life expectancy of 200k in most situations. Not to say it can't last any longer, but the odds go down after that number.

The battery light only comes on to tell you that the BATTERY IS DISCHARGING with the engine running. The usual CAUSE is the alternator or battery cable connections, NOT the battery itself.

CHECK YOUR BATTERY FOR PROPER CHARGE, & CONNECTIONS AT BATTERY TERMINALS, THEN CHECK YOUR STARTER RELAY CIRCUIT , & STARTER ITSELF FOR LOOSE CONNECTIONS OR MOUNTING BOLTS.

mine is under the passenger side of the rear seat. You have to lift up the bottomof the seat and it is under a flap. Stupid, huh.

Adjust the idle revs when the car is in either neutral or park. (2000 rpm is too fast for idle speed).If it is a late model car and therefore has a computer system then what ever you do DON'T TOUCH THE IDLE SCREW. You'll throw everthing out of whack. It needs to be done via a computer. Hope this helps
