| Video Discription | In this video I locate and repair a vacuum leak. Then I will show you how to use fuel trim numbers to determine whether or not the lean exhaust (P0171 and P0174) fault codes have been fixed. There are times when you have multiple problems, multiple leaks and the question is, are you confident enough in your repair that you know that check engine light is not coming back on? Without running any type of drive cycle, are you confident enough to give the car back to the customer? Understanding ST and LT Fuel Trim https://www.youtube.com/watch?v=oRX2V6_a3dc For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
