I just got done with this and my tune up (plugs, cap and rotor, fuel filter, and all the other stuff). Removing the EGR will help tremendously. The car responds so much better. Also I gapped my plugs at 32 and they are running really clean, not rich at all. The car is so much more responsive it's not even funny. You should be a pretty good self trained mechanic or know of someone that is. This is not for the faint at heart. This was a pretty difficult project and it took me around 3 hours total time. I used Simple Green instead of B12 or intake cleaner. Came out real clean and shiny. Thanks and LMK if you have any questions. This is the perfect time to change your spark plugs to.
