Hello All, I've been having similar P1516 issues once every few months, then once a month, daily and then several times last week. Until yesterday, I was unable to recreate my P1516 error. I checked the TB plug, wires, grounds, gas pedal plug/wires, etc but could never create. I was reading this string and thought to check the Throttle Actuator Control (TAC) which is mounted on the fire wall... No issue with the plug that goes inside the cab but when I touched the larger plug, I immediately could hear the TB cycle then idle rough then REP. The pins in the TAC and the female connectors in the plug looked shiny with no visible issues to the wires. I did notice that some of the female connectors appeared larger (expanded) than others even though the TAC pins appear to be the same diameter. I took apart the plug and removed each female connector to inspect. No discoloration on connector any so I don't think there was any current overload but when I used my carb jet cleaning tool, I did find that some of the connectors were slightly expanded perhaps due to vibration... With the jet tool still inserted in each connector, I gently squeezed the connector smaller then rotated 120 degrees then another 120 degrees to keep it fairly rounded. Again, this isn't a permanent fix but when reassembled, I've had no issues in the last week. Does anyone know if this plug can be purchased? Thanks, Scott
