intonation troubles

I played with a group yesterday and my intonation problems on my taylor 615 really stood out. It seems to be everything from open 1st position chords
to chords played up the neck. I really like the tones but being out of tune is very distracting. A local store has a larivee om-3k that I really like but not sure if I could trade even. I also am afraid I would be kicking myself later for getting rid of my taylor.

Anything you can do on to correct acoustic intonation?

Have a pro look it over. Saddle height and nut height are important. How old are your strings? Even if the tone sounds ok to you as strings are played they don't stretch evenly and this can mess up intonation.
