rebuild on my 88 shelby z 2.2 and am having trouble with the MAP sensor, code 13, have tried a different one but the same problem exists and computer goes into limp in mode.
Does any one have the electric reading for the MAP sensor and the solenoid?

Code 13 is the MAP not seeing a vacuum change, check for vacuum at the hose and if necessary, bypass the BARO just to make sure its not bad.

as always Simon, ready to share your knowledge, thanks.
Found what the problem was with the vacuum, the hose was on the wrong side of the sensor.
Ken tells me we have already done that, what he needs to establish is if the computer is operating properly. What values form the computer at the MAP sensor?
Does that make sense? I am way out of my league and learning like crazy.
I found this information and am assuming that this is what I am looking for.

(1) The computer will usually consider an increase of 1.80 volts or more over the minimum TPS voltage to be WOT.
(2)2.43 volts above the minimum TPS voltage during cranking will cause the computer to recognize Clear Flood request shutting off all fuel delivery.
So what problem do you have now? Still code 13?
What is the koeo vacuum reading at the MAP? Idling?

Still code 13, but now with that information going to check and see what the readings are.
