Removed EGR now have problems

[vex]

I tried the suggestion of holding the brake while the battery is disconnected. No go. The Tach is still sitting at 500RPM when off but displaying the correct RPM when on and running. Any other suggestions?

I've fixed the lean condition and all the bad drivability issues I was having. Unfortunately I still have parts of the car that are going to annoy me until I fix them. One of which is the Offset of 500 RPM.

The fix for the lean condition was just altering the sealant for the EGR. I believe the source of the problem was that I didn't really block off the EGR passage appropriately and so had to go back in with more Silicon sealant and place it between the main EGR passage and the two smaller chambers that follow back into the intake of the chambers.

I will make a new thread if it's not answered here in the next little bit. Unfortunately I do not have readily available computer access while I'm at my fiancee's. Just how it goes.
