I have a 1987 Cutlass Salon 5.0 307 vin code Y . Anyone know the how too's of replacing the TPS sensor on the M4ME Rochester 4BBL? i know you have to pull the top plate off of the carb , but do the metering rods/jets or anything else come out too-are they attached to the underside of the upper plate? And i need to know if anyone knows how to check the voltage of the TPS(what are the proper operating readings/voltage)? Any help is greatly appreciated guys!
