B15 Sentra (2000 - 2006)
Ok, something really weird happened today.
I started the car...it's idling...the tach drops to 0. The car is still iding, and it even revs, but no response on the tach. My safc had 0 reading for RPM.
After about 30 secs it kicked back on.
I'm not throwing any codes...
Any ideas?
