Best to take it to your Mechanic and just pay the money wont be cheap but you could save a heap in the long run  |
There is a howto on n54tech which demonstrates how to do this work at home using tools you can buy from supercheap. From memory, you need a slab of carby cleaneer, and wet/dry vac. You'd need to remove the intake manifold, and move the car (if its a manual) so that the valves are closed. Then spray the carby cleaner in whilst someone else vacuums. Repeat!
