Customer Question

My truck doesn't seem to be firing on all cylinders and is showing multiple codes starting with a p0300
JA: Have you checked the battery, particularly the terminal connections? Are they corroded?
Customer: No I keep grease on them so they won't corrode
JA: What is the model/year of your Chevy?
Customer: Silverado C1500, 2011
JA: Are you fixing your Silverado yourself? What have you tried so far?
Customer: Just research I don't have any kind of testing equipment. I may take it to the dealership but no one can get me in until next week and I have the afternoon so I'm seeing what I can do
JA: Anything else you want the mechanic to know before I connect you?
Customer: No
