A customer with a 2010 Chevrolet Malibu complains of a rough idle. After diagnosing the problem you believe the problem is a defective crank shaft sensor. The replacement takes about 1.5 hours and after completing the repair the problem still exits and with further testing you find the problem is actually a defective coil. You replace the coil and the vehicle is now fixed.
- Do you remove the part you previously replaced that didn’t fix the problem (that took 1.5 hours to replace) or do you tell the customer he needed both parts?
