Unit has gm v-6. Replaced sensor on foot pedal. Run unit for about 15-30 seconds and check engine light comes on. Actuator on top of engine freezes up and have no throttle. Restart and process repeats itself. Don't want to order actuator if another problem.
How do you pull code on this truck. Also, nipple on side of actuator with no hose. Look like for vac. hose.
any ideas
