Battery light on but if rpms are up to 3000 battery light goes out until rpms drop lower than 3000


If your battery is good, this means your alternator is not charging at the lower RPM as it should -- so you need to check for a loose belt that may be slipping, or the alternator needs work or replacement.

1991 300zx low idle, and low oil pressure!!!


650 to 700 rpm is ideal for the 300zx. the 300 was meant to be a performance car used at the rpms of 3000 and 6000. i have a 91 300zxtt that i use as a race car and a low idle is never really a bad thing as long as it isnt searching or loping
