Chances are the Timing gears or pulleys are not properly aligned. The Cam shaft and the Crank shaft must be aligned properly so that the valves and pistons are "in sync"

When to replace cam belt on 2000 ford focus?

Ford recommends it be inspected and replaced if needed at 60,000 miles.

Dealer cost is about $345 for parts and labor.
