Do the caps in a 4 mhz clock make a difference

[skimask]

Lastly, you want XTAL caps of 15-33 pF (not 0.20pF or 0.22pF). It should not matter the value as long as you are in the ballpark – they should run your XTAL near the stated tolerance for the XTAL. I cannot image persuading the XTAL to vary by a percent or so day to day as suggested earlier in this thread – maybe I have been lucky the last 10 years, who knows.
Good Luck,

I was throwing out ideas earlier. I've never tried to see how far I could 'pull' a crystal or even if I could do it.
But you're definetly right about reloading the timer. A guy should add a number to the timer rather than reload it with a fixed value in a case like this.

And I think it would really help in this case to see some more code...

I Used the code from Dogan Ibrahims book Pic Basic programming and projects.
Project 16 I copied the code onto my laptop and do not have the time to copy the entire thing out here. The main point of my question was if the caps could effect the clock and I understand (by the answers) they can if they are way out I really apprecate all the help and will publish the code if you want it but I just wanted to understand the relationship between a clock and the 22pf caps.
Thanks again
