Ok. You really can only check spark plug since you're away from home and don't have any tools (The parts store will have some, but you can't buy everything for doing say a leakdown test, which requires a shop air compressor. If it's cylinders 1, 2, or 3 (P0301, P0302, P0303) then that's the back 3 cylinders. From right to left, cylinders are numbered 1-2-3. You'll have to remove the right cowl screen (remove washer line clips {don't drop em!!!} then just pull up on the screen) then the 2 screws holding the plastic piece the right screen sits on and the piece, then reaching behind the engine on the right side of the car remove the 4 Torx screws holding the ignition coil and set it aside (on of the coil screws holds a radio capacitor). The plug wires and plugs are now accessable WITHOUT REMOVING THE UPPER INTAKE). Twist and pull of the affected plug wire. Then remove the spark plug. (Spark plug socket, a 2-3 inch extension, ratchet) The plug replacement interval is 100,000 miles. If you're over that and they haven't been replaced yet you might as well, they'll be pretty warn anyways. Check the plug for carbon tracking on the insulator (thin black lines burned into porcelin) and excessive gap. If you find either replace the plugs and plug wires. If it's cylinders 4, 5, or 6 it's easier because that's the front 3 cylinders. Just twist and pull the wire off, remove the plug and check for the same things previously stated. From right side to left, cylinders are numbered 4-5-6. Try to see if the parts place carries Motorcraft plugs. If not don't go with any high dollar split tip plugs. Plug wires aren't too bad to do, easier with Motorcraft wires as they are the right size, but doable if you take your time. Just do the wires one by one. DO NOT SKIP DOING THE PLUG WIRES IF YOU'RE DOING PLUS. IT WILL STILL HAVE A SLIGHT MISS.
Otherwise, you'll have to get it home or the nearest shop.
