The S2k forum doesn't get a lot of attention and with the number of people in the basement with S2k's it's probably my best bet. Anyway.

My mom started her S2K today and the digital tach was stuck at 10k rpm and it was blinking irratically, but the engine was at a normal 900ish idle.

She wants me to look at it tomorrow. I was going to check out the VSS sensor and was just wondering what else I should look at?
