Shop Lincoln Vacuum Pumps

I have a 1990 Lincoln Town Car with the 5.0 that has about 153000 miles on it. A couple of years ago the car was surging and dieing while driving it, i took it to a shop and they fixed it,it was a vacuum leek under the upper plenum that went to the map sensor. The next summer it started doing it again so i took it to a different shop and all he did was get into the ecm and mess around,averaging certain things if im not mistaken like the tps and map sensors,i dont know nothing about that stuff its just what he told me i think,anyway over the winter i ran somewhat better getting 10mpg c&h but the car never got up hot enough for the heater to work and the gas gauge goes crazy now up and down all the time and it started surging again,so i took off the upper manifold found out it didnt have a gasket and the map sensor was capped off so i put on a new gasket and ran the vacuum line to a new map sensor,and it runs great now(15mpg city) except it revvs up high on start up and idle back ok and it dies at stop signs.ive tested the voltage at the tps i was getting the correct readings before i took it to the shop now im not its reading 5.25 with the throttle closed,and the new map is reading 2.89 constant it dont matter if you vacuum pump it or not,the one that i took off a motorcraft reads 2.75. so stupid me i have my wife run it down to same shop as last time for the dieing at stop signs he said it your map sensor but adjusted the tps i think cause now it wants to pull a little while stopped with the brake on,but know i have three maps that all read the same or close to reading 2.89 & all but one is new.the service engine light tends to go off while driving till you idle down then it comes back on.whats going on??and also the gas gauge never acted like this till i took it there.i hope this made since cause it dont for me no more.so basically what happened i think was the first shop capped the map off,the second one did something in the ecm,then i fixed the real problem and then the second shop fixed the tps and tried to get her for $200 to put on a new map and that included the diagnosis ,she left only paying $90,i went and got a map but all three read the same??

What codes are being set in the computer?

Why would you do that. The car is equipped with a MAP sensor, it needs to work. The coolant temp sensor is just as important as the MAP or MAF.

You're still getting MAP sensor and CTS codes so you still have a problem in the circuit.

data stream that mustve been what the shop was into i mustve overlooked that earlier yes im still getting the map codes,but the three maps i have all read the same. i probe the middle wire and hook up my volt meter and hook up the vacuum pump and all three read from 2.90 -2.75 with no vacuum applied and it dont matter if i apply any or not. i assume im doing it right. maybe not?before i took it to the shop that did something inside the ecm, i used to be able to get the correct reading on the tps(i think it was just below 1 volt), now it says 5.25 with the throttle closed or open or anywhere in between.but i have tested it yet since this visit to the shop when they fixed the dieing at stop signs and the high revving(2000+/-400) at startup.know it dont die and the revving is down to where it should be at start,the heater now works,seems like the passing gear is alot better..the car has a mass air on it, is that a conversion or did the 90 town cars have that?

I already told you that just because you have a MAP code doesn't mean the sensor is causing it. There is a problem elsewhere in the circuit that needs to be found.

ok sorry

dude i cant thank ya enough,thanks ,im off the next two days so ill get to it and see what i can find

No, this car came with both sensors and they both have to be operational. This is not an add on here.

Did they do a MAP to MAF conversion on this?
