I was traveling from out of town and had my check engine light come on in my Ford F150. The truck was not accelerating well. The Kal Tire representative checked the truck and oil level, and said it appeared a sensor was needing to be replaced. One was ordered overnight, but unfortunately it didn't fix the problem, so they removed the new one and replaced it with the old sensor and didn't charge me a dime! Really impressed by the staff and service they gave me! Thank You so much!
