EGsedan and harness, d15 dizzy with F22b2 non vtec ran like a dream, now it won't make it above about 2500-3000 rpm without acting like it's bouncing off a rev limiter slowly, in gear and out..ICM maybe? Checked the ignition timing rotating the dizzy and it about fell on its face
A little confused :/

Use the F22 Distributor? Sounds like the car is protecting itself from damage from an odd component. Same thing happens when you removed the plug from the IACV or similar device.

Can't use the f series dizzy, the swaps wired with the eg harness so no plug for the coil..she ran perfectly before but today I left hard on it and it "like" died, it idles smooth (a little lower than before) but the second I try to rev up or run any gear further than like 2500 rpms it starts stumbling like a low set rev limiter..

Sounds to me like its in the safe mode I explained, I would just wire up the B series harness (figuring you're using an F ECU or a chipped ECU) to the F series distributor. Otherwise the ECU isn't going to agree with it very well.
