have a 92 Chevy c1500 tbi with idleing issues, i've replaced fuel filter, fuel pressure is good as well as injectors, fuel pressure reg, plugs and harness, EGR and MAP Sensor. All the voltage checks are good on the MAP sensor, however when i disconnect the wiring connector from the map the truck idles fine, reconnect the wiring connector and it stalls out. this is the 2nd map sensor i've tested both with the same results..any thoughts?

so you're suggesting replacing temp sensors to fix the map sensor problem? i know there has to be an underlying problem somewhere down the line of the map sensor, i'm just at a loss as to where else to look.
