2007 maxima
 

Sluggish & loss of power while accelerating from a stop or cruising at 20-30 MPH. Any suggestions on what's causing the problem.

is this the first this has happened? have you had it to a nissan dealer for a tune up recently?

I just had the timing chains, timing chain guides, tensioners & O RIngs replaced. It idles perfectly.

Thanks so much to both of you.
