Ah yes, my Sentra clutch feels incredibly wimpy. Almost like I have the torque converter of an automatic under control of my right foot. Many Subaru's I have driven are this way too. What a shame, clutches these days are designed so a 14 year old complete newbie to driving could get in and get a fast smooth start on the first try. Then again, this is also the day and age where some cars come with stability control that can't be defeated.
BTW, as for your problem, it could be the mass airflow meter. There was actually a letter about something sortof similar about a Maxima in the Technical Correspondance section of Road and Track. Basically the problem was the K&N filter. You have to oil the filter VERY lightly otherwise it does become a problem. Have you by any chance serviced the filter lately?
Also, a check engine light would probably come on if there was such a problem? I'm not sure, my car only has turn signals, a high beam light, and a no battery charge light.
