View Full Version : Searched - Nothing useful. Tach/car fluttering upon startup

07-15-2007, 11:24 PM
I tried searching and didn't really find an exact answer for my question.

On a 94 SC I am looking at buying, when you start the car and watch the tach, it shoots up to about 1,000, drops to 500 and then idles in between there.

If you listen you can hear the motor rev up also.

Now, I have heard stories of a bad DIS module or CPS causing this, but I'd like to hopefully get a real answer before I drop the money for a DIS.

Any help is appreciated.

Have you verified the check engine light is functional, and if so, is the light coming on?

I'd pull codes to start with and perhaps isolate the cam sensor by pulling the connector off and running the car to see if anything changes.

I know the Check engine light is on, but as far as I know, it's only for the blocked EGR.

I'll see if I can get the seller to take a look at it as it's in Peoria - about 2 hours 30 minutes away.

I might also add, the car runs fine after this little flutter, so it's not a major problem as of yet. However, with it being an SC, I'm hoping to solve it before I may become a huge problem. :p
