Mine did that for about a week...then the belt chirpped one morning, the noise went away and it's been fine eversince. Idle egt's went down and the CEL is on P0404. Been like that for almost 2 years now...

Funny you should bring this up today...My to-do-list for to day is to "fix" the CEL with EFILive...:D

When you removed did you have any issues How about pcv being in pump. did you remove and plug lines. I have turned off egr system with efi and blocked valve Remains for decoration.
