Tachometer behaving strangely?

[mintchoco]

I have a 96 Integra automatic.

Lately I've been noticing that the tachometer, while stepping on the brakes, goes as low as 600 rpm (I think normal is just under 1000rpm). And then also when I'm driving and it shifts, right after it shifts, the needle dips to about 1200 rpm before it bounces back to 1500 rpm as it should.

Anything wrong? I don't think it used to do this before.

stepping on the brake...like at a stop light? from engine spec, i think your car's idle should be 700-800 rpm in part or neutral.. check that first.


dips to about 1200 rpm... what was the RPM before the gear change?

check stuff like air filter.. distributor.. that kinda things first!
