Can't find my egr valve on my 2003 gmc Savannah 3500 6.0l. I can buy it from the store which make me think that I should to have it. I am trouble shouting p0300. Have new spark plugs, cables, coils...
My dad just got waxed today for over $1200 to replace his water pump and I totally could have done this shit for him. $450 for labor when I’m sure it took them MAYBE an hour. 🤦🏼♂️🤦🏼♂️🤦🏼♂️
