Code 33 any ideas ?
I have codes 32and33 on my car(91 z28 5.7 tpi). Iknow that the 32 is because I don't have my egr connected right now. I can't figure out why I have a code 33 though. All of my vaccuum lines are connected. The only thing that seems questionable to me is that the PCV valve doesntvseem to seal tightly in the valve cover grommet. Any ideas ?

Clear the codes then disconnect and plug the vacuum line from the map sensor start the car and see if the code comes back (the ecm will use a preset value for the map sensor)
It may be a vac leak.

Ok, I'll try that. The ses light only comes on at cruising speed though. And I don't think I can drive around with the MAP disconnected, can I ?
