Well, this is the first time I have noticed this since I got the car in June. Today went out to return a movie, then stopped for some fast fod. After getting in the car to drive home after eating, car started fine, but ran like it was missing on a couple cylinders and you had to keep on the gas a little to keep it running. Tried shutting car off, and re-starting but it did same thing. Decided to try driving it a little ways to see if it would clear up and it did. After a block it ran fine and didn't act up after that. I changed the plugs and wires on it when I bought it and have put about 10K miles on since then. I used the NGK Platinum plugs, and Taylor 8mm Spiro Pro wires. Only thing mechanically I've changed on the car is I put on a new water pump when I did motor mounts after buying the car, and I have Wynn's downtubes with no cats, glasspack and two Spintech mufflers for an exhaust. I check the spark lug wires when I got home and all wires were firmly attatched.
