Well as noted get a test of the engine, BUT, when did it start? You said she was on a 2k trip, but when did the miss start? Kinda hard to blame the woman for not noticing it, but how many guys are just as inept at taking care of stuff? Get a good checkup at a shop, check oil for gas smell maybe spend $25 for oil analysis if you really like the vehicle. My son has a f150, has 150000 on it the coil pac went out it started to miss, we ran the codes replaced the suspect, ended up buying another just after we replaced 1st. So no telling when the thing quit.
