I think your getting a random misfire. Common issue in 2g's with 6 bolt motors. I'd just start saving for DSMlink because thats the only way your really going to get rid of it. By the computer getting a CEL it starts looking for other problems. You could do the Baro Wire mod but I dont trust that at all. I think VFAQ has info on how.

Try this. Next time you are at cruise and it starts to do this, flip the key off and back on quick and see if it goes away. As if you are turning the car off then back on. If it goes away, then you are definatly getting a random misfire. I use to have to do this on long trips, 3+ hours of driving at a steady speed it would start to shudder. I just flipped the key off and back on and I was good for quite a while. My money is on that!
