I bought a part for my 2002 Ford Focus from the dealer and planned to replace it myself. The new part, a DPFE sensor, required rewiring so I decided to take it to a shop. After being referred by a trusted friend (the owner of Auto Sports Import-Rick Cameron) I dropped by Quality Auto Electric for a quote. The service manager (Dan) quoted me a small price for the repair and told me he would replace it right then and there. After Dan attached the new harness and sensor I pulled my wallet out to pay and he said "don't worry about it".
