hey welcome!!
need to know the letter that comes before the code but heres what it could be
P0032--HO2S Heater Control Circuit High (Bank 1, Sensor 1)
P0042--HO2S Heater Control Circuit (Bank 1, Sensor 2)
haha P00 ahhh
U0032--Vehicle Communication Bus A (+) High
U0042--Vehicle Communication Bus B (-) Open
either way it sounds like you have either a loose or broken wire in there somewhere.....

Umm... Considering this is an OBD1 vehicle, these are not P-codes or U-codes. They are generic OBD1 codes.
32 == EGR open command did not change MAP sensor signal. Normal EGR flow should cause slight decrease in manifold vacuum which would change MAP sensor signal.
42 == The EST signal did not change when the ECM applied bypass voltage to the ignition module.
Don't know about the code 42, but I'd have a look at your EGR valve as that is most likely the cause of your poor idle.
