interesting findings

disconnected maf = no change
disconnected egr vacuum solenoid electrical connector = no change
disconnected evap electrical connector at vacuum block = no change (ran worse without it)
disconnected map sensor electrical connector = doesnt act up anymore?

does anyone when the check engine light is lit for map sensor fault what sensors the 94 obd1 computer ignores?

next is disconnecting each o2 sensor one at a time with map reconnected to see if there is a change.

thank you guys for putting up with my extensive tech post with this problem. i am learning alot about this engine due to this and most of what im learning is from you guys, especially greenformula92 and LTb1ow. in a roundabout way the suggestions you have posted on other threads for lt1 issues and mine have helped me narrow this down to a sensor problem.
