My question: While cruising down the street at speed, roughly between 1500 and 1750 RPM, my car will begin to feel like it is lunging forward or dropping back. It almost feels as though not all of the cylinders are firing. This doesn't happen during acceleration, or when the pedel is depressed enough for hard driving but only while at cruising speed. I was hoping someone could help inform me whether this was a problem with the sparks, or the injectors? Thanks.
