I was driving down 57 today and was going through a 55mph construction zone. After the 55mph ended I punched it and I really dunno how to explain it but once I hit about 65 it just got real bogged down and was chuggin/jerkin. I lost power, it looked like the speedometer didn't know what was going on either, but the car didn't die. That happened like 100 yards from an exit so I got off and cruised real slow for a few minutes then turned around (it was a country exit, no gas station or anything). It seemed fine after that, I drove another 300 miles or so. No CEL. I know someone is going to say coils but I drove with bad coils before and I don't think that's it. Any ideas?
