Suggestions -

Remove/clean EGR valve and passages.
Check/clean/replace IACV (there is a procedure for this, ask your dealer if you can view a service manual)
Reset ECM (Pull Hazard fuse for 30 seconds to a minute)

Verify cam timing is correct.

Insert jumper to advance circuit (white covered 2p jumper plug on the d-side fender near the strut tower, insert something to cross those pins, like a safety pin)

Loosen dizzy and attach timing light, check/adjust timing as necessary.

Idle speed is not adjustable, the IACV takes care of it.
