Hello my name is ***** ***** thank you for your question.

What brand spark plugs did you install?

Customer: replied 1 month ago.
Hey they are denso 3119.
Expert:  Jay replied 1 month ago.

Ok, first things first. We need to put NGK spark plugs in this truck, non platinum. These trucks are very sensitive the the brand spark plugs used. The Denso plugs can certainly be causing a running issue and starting issue. So can we change those and then recheck the vehicles operation?
