Thanks for the quick answer, guys!
I kinda figured it was the crank pulley, but sometimes the Haynes manual is confusing.

This is off topic, but, anybody know how to set the timing correctly on a 92 accord? I kinda figured it out, but the motor still idles funny. It drops from 1,500rpms down to 1,000, then to 500--and back up. What is a TDC?

Thanks
