So tonight I was driving home, after getting my car back from the shop (had some tuning issues) and decide to do a 25 mph punch from a roll. Of course the car takes off and runs like a bat outta hell. After that my tach falls to zero and won't move. So I pull in the garage get a SES light. I then scan the codes get P0343-Camshaft Position Sensor Circuit High Voltage. I erased the code and drove the car and everything seems fine. That is after the car is started. It seems hard to start. Also, my tach is still at zero. Can someone explain what this code is and if it's a big deal?

For the tach issue my Helms says to do an instrument panel check, sweep the tach with a scan tool, then go from there...

www.gearchatter.com/viewtopic9358.php for the code. If everything was fine before bringing it in I'd head back there.
