![]() Does it still idle too fast after it's warmed up. Remember, u have a fast idle when it's cold. If so, check to see if it's sticking.

It's because when u are adjusting your timing, u don't want anything else but u adjusting it. Sometimes there is still a little vacuum left in the hose, or maybe your car is idleing too fast, and creating a vacuum. U want to rule out everything else to get the timming more percise.
