Car jerks slightly at 90km/h...(50mph)
1988 Crown Vic LX. 5.0.
Ever since I got the car 4 months ago, every now and then on the highway, the car jerks a bit at 85-90km/h. Sort of feels like its missing or something. It feels almost like a tranny problem, but seeing its at such a precise speed could it be tires? The tires I have on there now are shit, so I'll be replacing them soon anyways, wanting to throw on some 235/60/15's. Anyways, anyone have any idea what this could be? It only does it sometimes, but its noticeable, and I want to keep my baby running forever. Thanks.
