Lately my car has been acting up. Its a 1993 Honda Accord, with about 125k miles on it. A couple of days ago on the highway it shook and the rpm would go from 3 to 0 and then back to 3. A few times it also stopped by itself. It would start right back up though. A friend of mine told me that it wasn't the transmission as I had originally thought, but it may have something to do with the fuel injector. Also, when it does turn off the oil light blinks, but I know that there's sufficient oil in the car. Please help!
