Car: 65, auto, 289, FMX I was driving down the highway (maybe doing 50 mph), and suddenly, it felt like the car shut off. I hit the gas and it would do nothing and I started to pull on to the shoulder and I realized the car was still running. I barely pressed the gas, and it kept going but was running like it was sort of in between gears just sort of pulsing (hard to describe) It was like it was going in and out between neutral and drive or something like that. I managed to get where I was going and back home (about 30 miles round trip) with out it happening again. Cruising around the neighborhood at 15 - 20 mph is not a problem but again today, I gunned it and it hit this not so sweet spot again and it started to do the same thing. Any thoughts? Where should I start one this one? I got an oil change about a week before it happened but I am not sure if there are any mistakes they could have made during that process that would cause this. Fuel filter is brand new also.
