Default weird idling issue
It will idle very low and die unless I give it gas. When I unplug the MAF it idles normally. What could this be?

Probably a dirty MAF. Buy some MAF cleaner from an auto parts store and git er done.

Dirty MAF or vacuum leaks. When you unplug the MAF the ECU resorts to speed density in which vacuum leaks raise the idle if the IAC can't compensate.

Could it be because I deleted all the air and egr stuff on the old wiring and ecu? Went from 93' to 95' wiring.
