 Cylinder layout for 99 Grand Marq 4.6L
First post here.
Engine is misfiring something bad, and OBD reader tells me it's cylinder 4.
Unfortunately, I haven't been able to find a layout of the cylinders on this vehicle. I've been searching online for the past hour before I found this site. Can someone tell me the layout, or point me to a site that has this info?
FWIW, I changed the spark plugs and wire set a few years / 40k miles ago with quality brand name parts, and am surprised I'm having this problem so soon. Don't know if this is a possible reason, but last night was the coldest it's been since spring; still, nothing drastic.
Also, I know driving it in this condition worsens my gas mileage by at least 12.5%, but is there any other danger driving this car like this? I'm about 90 miles from home, and all my tools are there. If I have to, I'll buy whatever tools I need to do it where I'm at now, but if I can avoid having to buy more tools without damaging the car or winding up on the side of the freeway, I'd like to get it home to work on it.
Many, many thanks in advance!
- Dan

I am a relative novice to car repair. I've replaced plugs & wires and this year I learned how to replace brakes and did so on three vehicles. It looks like I'll be learning how to replace the exhaust system very soon. "Back in the day" I'd been known to replace radiator or two and a water pump once, but that was before you'd have to take apart the entire front end to do so.
