ok i have a 90 camaro rs 3.1 v6 i was having troubles with idle and temps and oil pressure also it was stalling so i replaced

oil pressure sending unit
alternator
plugs
wires
cap and rotor
battery
all vac lines (but my brake booster broke so i just capped that line)
pcv valve
pickup coil

then i didnt have the stalling problem anymore the high temps or the high oil pressure then i was getting a code 44 and i changed the oxygen sensor then once i changed that i ran it for about 25 minutes to get it to normal operating temp and it throws a code 34 so i cleaned the iac valve with carb cleaner and i used seafoam. seemed to run great for about a day then i went and drove it to the mall and on the way back i was in some heavy traffic and code 34 and 35 came to the light. it seems to run the same still but i thought that if i had a MAP sensor i didnt have a MAF? what do i do im supposed to get an inspection tomorrow and i cant if any lights are on.. and this is my DD. thanks for any help in advance.
