LT1 Code 33

LT1 Code 33
If your LT1 started running really rough. Missing badly especially at low RPM and you limped it home and got a code 33 "MAP Sensor". Would you order a new MAP sensor and try that first? I know what the FSM says but I do not have the means to test it the way the charts are laid out.

RE: LT1 Code 33
I would start by checking the vacumn connections as well as the electical hook up. You have to remove the MAP to inspect the vacumn connection which I think is on the bottom of the MAP.
Don't know what a new MAP would cost, but I suggest you consider gettin it diagnosed before replacing a part that may be good? Hope it's just a loose connection or something simple?
