Default please help!!!!!!!

Just curious:
has anyone on here with an automatic c6 with H/C/I had a problem where you sitart your car and the rpm's are working find.

Drive car for awhile but once you cut it off and start it back up the rpm guage lays over on the crank up ... but lays flat at idle . Car then goes into a boating mode and the code p0336 pops up when you scan it.

If you clear the code the rpm's still doesnt work but if you let the car sit for awhile the rpm guage will enventually start working again . Now once the car runs awhile and you cut the car off again its back to no rpm's . Thanks any info would be highly appreciated !!!!!

Try a "crank position sensor relearn procedure" any tuner can do this--Quite common when doing a cam change or gear change----
