i sure wished that i could have found this site sooner. i was told by a shop that it was the steering gearbox, i had it replaced, some $760.00 later the problem still existed. then they said it was the power steering pump. $250 parts & labor, so i went and bought the pump and installed it myself. problem still exists, do i need to replace the sensor and evo? if this fixes the problem, am i entitled to a refund.
