Hi Kenneth, Thank you for your review of your experience at our company. I am sorry you do not feel you recieved any value in the service for the money you paid on your visit. We did spend the time that you were charged for on your vehicle. We actually spent extra time checking the chewed up wires under the hood of your vehicle. We diagnosed the four computer codes that we scanned for. We performed the evaporative emissions (smoke) test. You stated that we were unable to tell you what was wrong with your truck. That is not true. We told you you needed an egr valve, map sensor and tps sensor. We also told you that you may have other issue because of the rodent damage to the wiring under the hood. All of that information is printed on your receipt. Please call or come by and I will be happy to go over that information with you.
