Brother's Altima is pinging on light acceleration. Also, engine stumbles at idle and settles down a bit lower than usual. Car has 47k miles, well maintained. Perusing the Nissan forums has me believing that this is "normal." Any things in particular to check?
The pinging is a known problem. A decent decarbonizing treatment may help. Idle, I'd clean the throttle body and relearn the base idle.
do the 3.5's still eat the pre cat or was that the early 2.5's?
Early 2.5's ala SpecV Sentras.

This. Does he usually granny it around? A couple techron treatments and a cleaning of the iac, maf and throttle body plus an Italian tuneup wouldn't be a bad start.
Okay. I'll tell him to take it out and romp on it a bit.
It needs premium petrol. How about a knock sensor?
