Sounds like a dirty throttlebody plate or your electric accelerater assembly is going bad. Clean plate a retest, if it happens more ofter you should replace the gas pedal assembley and the throttlebody assembly.

Have you checked the gap on your spark plugs and do you have coil packs or a distributor? In either case they could be bad or cracked.

The motor on the transfer case isn't working.

Several possibilities: Bad fuel pressure regulator, leaking injector, but most common is bad coolant temp sensor.

It's called the EATX fuse. Marked on the fuse panel lid. You can't test it this way. Scanner is better. What seems to be the problem. Codes.

Over heating can cause a cylinder head to crack or burn a valve/gasket. Overheating is a sign of a stuck thermostat, a blocked radiator/collapsed radiator hose .. or a cylinder head problem First, check the dipstick for grey/creamy sludge. This means water/coolant has found its way into the oil system via a faulty head gasket/cylinder head problem. Then .. if you know what you are doing .. do a compression test. If you're not sure what you are doing .. give a mobile mechanic a call and ask his advice

The easiest way to check for a draw at the battery is to unhook the negative battery cable and hook a 12v test light in between the negative post and the negative cable. The light should light brightly if there is a significant draw. You simply unhook circuits till the light goes dim, or out. I always start at the alternator, even if it has tested good. An alternator can still charge with a burned out diode which will cause a direct short to ground and drain a battery like nobody's business.

fuel filter replacement period is in the owners manual and depends on fuel quality and driving conditions if you get water in the fuel , it should be change immediately, even if it was just done dirty/dusty conditions , change it more often around now would be a good time to change it and then under normal conditions again at 100.000 miles

a few things to check with this problem: (1) ck all the interior lamp switches to see if there all set to "auto" mode an not to "ON" all it takes is one and they all stay on (2) ck all the door switches to see if any look funny or damaged in any way , as if any of them are not working the lamps will stay on , replace any that are not working properly (don't forget the hatchback) (3) its actually a plug in module next to the fuse panel that preforms this dimming function , as a last resort I replace it
