I just arrived in the northern Atlanta area (Dunwoody) for my son's club volleyball nationals (July 1-4). I'm driving what was Nate's 2000 Hyundai Elantra (116,000 miles). We don't have any idea of the maintenance history because we just got it a year ago or so.
Things were going great (getting about 36 mpg) until I was about 20 miles from my destination. I then noticed the car sounding like it was occasionally missing. It started getting worse, then I could hardly give it any gas when going uphill or it would almost die. It got continually worse - I was sputtering along on the shoulder, hoping to reach my hotel. At one point the engine completely died, and when I restarted it it was running completely normal. I went a few miles and the sputtering started again, so this time I pulled over on the shoulder and shut off and restarted - running good again. This got me to my hotel, but I definitely don't want to leave for Chicago on Saturday afternoon without knowing what's going on. The behavior makes me suspect that it might be a clogged fuel filter, but I guess there's always the timing belt to be concerned about.
Any suggestions? Hopefully I can find someplace to take it to tomorrow afternoon. The hotel I'm at runs a shuttle to the mass transit station that takes me down to the volleyball venue (Georgia World Congress Center - right next to the Georgiadome) so that will help if I need to leave the car off someplace. (I see that there is a Goodyear Auto Center just up the road, so I might give them a visit.)
I should add - no check engine lights or such. Just rough running, especially under load.
