In this video I dive into a GMC Serra Denali 6.2L (similar to Chevy Silverado) with a customer complaint of sticky shifter, a service stabilitrac message, and a rough idle with slight hesitation on acceleration. After a quick look at stored codes I also found code P1175 (similar to P1174 B1) and an obvious lean condition on back 2. Watch as I take a closer look and uncover the cause for each of these symptoms and find the fix.
