loss of power/rough idle

I have a 97 Max (auto GLE with 40,000 mi) that recently seems a little sluggish at low speeds, on the highway it seems much more noticeable (60-85mph). Also I noticed the engine idles a little louder, almost sounds like a light rattle. The service engine light has not come on.

I'm not sure if these 2 issues are related, the only thing that's changed is that its much colder here in Michigan. I bought the car in Oklahoma where its spent its entire life until the past 3 months. Not sure if this matters, but I only use 93 octane gas in it, and try to avoid the oxygenated stuff. I might be able to borrow a OBDII scanner, could this help indicate the source of the problem?

thanks in advance

if your knock sensor is down, you will lose about 15% of your power. It will turn up code 03 04 if you pull your ecu codes and it does not trigger a check engine light. It is not responsible for rough idle or rattling though. You basically noticed poor throttle response and loss of power.

is the VTC rattle only inherent to 3rd gen Maximas? I was unable to verify this.

also, I ran the ecu test and got 05-05, no problems...could it be something in the exhaust system causing that noise??

the VTC problem ONLY affects 92-94 Maxima SE. Lotsa things can cause noise in the exhaust
