Replace thermostat, the old one was hollowed out. the van ran well enough. Now when it gets to operating temp. she has power surges while idling, and at traffic lights she dies. Have replaced a few switches, oil pressure switch, Tps, and temp. sensor.
What is the problem, and solution or am I just suppose to hollow out another thermostat?
