Slow it down and play it in every rhythm you can think of!
Swung, inverted swung, triplets, crotchet crotchet quaver quaver, whatever takes your fancy

then speed it up and then play it straight. That way you have your head and fingers round it in every way possible! If you can play it in all those rhythms then you can play it straight. Plus it'll be more controlled after all that too

Good luck!

My teacher also tells me to play with 'all different types of bowing'
ie: separate bows, two slurred two separate, 3 slurred 1 separate, 2 separate and 2 slurred and so on, any type of combination you can think of!
just like ffliwt suggested exercise it will get your 'head and fingers' round it in every way and it will 'cement the piece' in you!
I have to do this with my pieces and my exercises every day (teacher's orders

)
Was about to post the same thing! (wonder why..)
Look up the bowing variations for Kreutzer no.2
If you do even the first few it'll fix just about anything.
Failing that, the orchestral player's best friend - fake it! (works well unless you're all doing it!)
Keep your bow going but actually aim to play the first in each set of 4 semiquavers or whatever. This relaxes you slightly and helps you to keep up.Then when you've got the pace every 2, and gradually fill in the ones inbetween as you dare. Sounds silly but works surprisingly well
