I have a 2002 Ford Focus ZX5 with about 108,000 miles on it. It’s driven far distances, about 700 miles round trip, a couple times a month. About about three times since last summer, approximately halfway through one leg (at around 200 miles in), the engine starts jerking when accelerating. It doesn’t happen on every trip, and seems to only happen on hotter days. (Driving around town short distances, even at high RPMs doesn’t present a problem at all, it’s specifically after a couple hundred miles.) The engine light has flashed, but not every time the jerking occurs and hasn’t stayed on, and the code that was pulled doesn’t seem to be helping either the mechanics or Ford know what the deal is. I’m looking at having the whole transmission swapped for well over a grand, but with the disclaimer that it’s not a guaranteed fix. Has anyone heard of this problem before that might be able to save me time and money?
Thanks in advance to anyone who can help!
