I was driving my SC around tonight and I noticed my tachometer just stop working, and fell to zero, then the CEL came on. I was like ~~~?! My friend sugguested shutting the car off so I did, but still didnt work. It ran fine though, norm water temp, and norm oil pressure. A few minutes later it magically stared working again. No CEL and a functioning tach.

On my way home, the same thing happened. It dint work w/ CEL light on, then magically came back on w/out CEL...


~~~:confused:

and if the camshaft position sensor completely dies, it'll only start up 1 out of 3 tries (on average). Just keep trying.
 
Most likely the cam position sensor, but it could also be the magic sticker on the tach assembly that likes to fall off and catch on the arm.
 
I had that problem on my 35th but w/o the cel. It was the DIS module. I'd tried everything w/o success but swapping the DIS fixed it. It always started and ran fine but the tach would come and go. Did this for 2 years.
