new to the site. RPM needle bouncing all over the place

[trucruiser]

Hello everyone, Im new to this site and to Infiniti.I just purchased a 1995 J30 with 150000 on the odo. The RPM needle fluctuates and there is a check engine light on, I did notice when the RPM needle is working and not bouncing that the check engine light os off, as soon as the needle starts acting intermittent the light comes back on. has anyone seen this before?The speedometer works all of the time so far.

Thansk in advance.

Welcome to the site. Like Yoda said, pull the codes before you do anything else.

p.s. It's Infiniti not Infinity

Fixed it, Thanks

A tip when searching for stuff on eBay, spell Infiniti both ways as alot of people, including people that own them, don't realize that it is spelled Infiniti instead of Infinity.

Bouncing tach needles have always been a result of a bad ground (low voltage) in my experience. Not saying that is what the problem is but something to think about.
