i got the codes, now how do i fix them?

ok i just ran a self test (with paper clip) on my 94 Blazer 4.3 code W automatic 2WD blazer.......... here are the codes i got:
23: which is Manifold Absolute Temperature (MAT) sensor or circuit / low temp
66: which is Air conditioning pressure sensor circuit.

Does anyone know how to fix any of these?? thanks in advance!

Also could any of these cause a sluggish start in Drive? It seems fine the second i step on the gas, then about a second later it seems to loose its power and kinda bog down..........

Is there anyway to pull the ABS codes on a OBD1 connector?? I think this may be the cause of the above problem.

Thanks,
Steve

could a bad PCV cause code 23?? because i know i need a new one.

no one knows???

wow...........

ok dude you really need to chill if u know u need a new pcv valve replace it and see if the code goes away all of ur other posts are the same way people are more willing to help you if you just relax

I was reading my Haynes manual and it said codes 37 38 39 and 58-82 are transmission codes and represent internal transmission problems and should be left to a dealer service department or transmission repair shop. Anyone know about this?
Im not sure what the site was that i saw code 66 was a air conditioning pressure sensor.......

wow i figured it out. There is a lot of help on the Blazer forum here...... :screwy: the code 66 was for my 3-2 Control Solenoid so i got it out last night, now i have to go get a new one.
