There's no need to delete the EGR. Fix the tube that goes into the LIM and you'll fix that vacuum lean 90+% of the time.
To the OP. Are you losing any coolant, blowing white smoke out the tail?
Sounds like you haven't done the wires, checked coils or found which cylinder is misfiring or if it's many.

The wires are not stock and look fairly new. I am not blowing any white smoke, and im not losing hardly any coolant besides the small bit down by the actual LIM. And no i have not checked the coils.
10-17-2011
Down by the lim? Please clarify (coolant elbow, lim end cap, tb gasket, lim bolts)
What wires are on the car? (please say ZZP, please say zzp)
10-17-2011
By the LIM bolts...and no not zzp

You took all the fun outta this post.
What kinda wires. Don't keep me guessing.

Alls I know is that the wires say Delphi on the coil connectors and Packard on the wires. I scanned it and got a "MIL is off" code and p304. Cylinder 4 misfire

Uh..do the wires have numbers on them?
10-20-2011
Numbers as in corresponding to cylinders? Yes. And they are all leading to the right one. I've began an LIM gasket replacement and have broken a couple old crusty vac lines. Any idea where I can get a full set for cheap for a 97?

autozone sells vac repair/rebuild kits, fittings and such, i think the tubing is separate tho. i just saw it last week for 15 bucks or so.
or hit the dealer.

Just finished the LIM gasket replacement. Replaced supercharger and throttle body gaskets also , ported and polished supercharger and polished TB, completely cleaned LIM itself; runs absolutely no better. Fantastic

did you try a compression check? test fuel pressure? is it still misfiring on #4?
if it is still #4 try this... move the injector to a diff bank. if the misfire moves its the injector. next try and swap the coil pack to another bank. if it moves its that coil pack.

Have yet do to compression and fuel tests...friend just told me to what you said; switch the coils...I'm not getting a code for misfire anymore but it seemed like it was at the top of the tach right before shifts
EDIT: Bad misfire starting at about 3500 rpm going up until shift..finally got the p304 code back
