showing a P 0340 code need advice

This morning I drove to work and things were fine but after 10miles or so if I pressed the gas and went above 2500rpm it would stutter and bog down, it idles fine and once it cools down it revs fine. The code is a crankshaft positions sensor please advise.

Erase the code and see if it lights up again. If it does then most likely it is the sensor being detected.

My guess would be you need to replace your crankshaft sensor.

Reset the computer and that seemed to fix it. Computer snafu

If you rec'd a code, it may be an early warning sign of a future failure of the Cam Position Sensor, or as you mention just a glitch, which could be the ECU, or the sensor having a bad day.

If it happens again, replace the sensor.
