MAP Sensor question
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?

Do you mean MAF? (mass air flow sensor)
and when you replaced it did you touch that thin wire? any foreign matter that gets on that can make that thing not work properly |
TBI trucks don't have mass air flow sensors.

I stand corrected.

Thats correct manifold absolute pressure sensor.

A bad temp sensor can also cause this.
