Only once in a while, and only for a minute... But when the gauge (tach) does decide to work, everything else works as it should. I think that these problems are related. And i'm hoping that if i get the tach issue resolved everything else will become right again. or at least i hope! Do you think that the tranny could be going out and that is causing the gauge to malfunction? I am under the assumption that the tach is read before the tranny. So if the trans doesnt know how fast the motor is spinning, it doesn't know what to do???? At least this is what i've come to understand
