I've had my Boss since last November, have around 2300 miles on it, and have had this issue from day one. When at idle, the engine appears to stumble slightly. It almost feels like a miss. You can feel a slight stumble and even hear a small "pop" from the side pipe. Sometimes I'll even get an occasional backfire from the side pipes on decel or downshift. I really do mean a backfire, and not that awesome snarl/braaap sound that we get on the overun. The baffles have been removed, but, like I said, this has been happening since I got the car. The car is bone stock-no trackey/intake/exhaust/tune or anything. A week after I took delivery I took the car back to a dealer that claims to have scanned the ecu for trouble codes. I was told there were none, and that without a "check engine" light, they didn't think anything was wrong. I was also told that these engines idle a bit rough and that is what I am probably feeling. I'm finding this pretty hard to believe as you can also feel hesitation or resistance when you are in neutral, just slowly raising the rpm up. It seems to shutter/stumble most noticebly in the 1500-2000 rpm range. After that, I imagine the higher revs are just making it less noticeable. I haven't had the opportunity to listen to, or drive, another Boss so I really can't say for sure that this is NOT normal. I just can't imagine that this is normal, especially since I haven't seen anyone else mention this here. I plan on getting the oil changed in the next week or so. Anyone have any ideas on what this might be, or what I can ask the dealer to do?
