I have a 2006 GMC Sierra pickup. Since I started using E85 gas, mileage has dropped drastically. Can you tell me if I need to ues a different type of spark plug? Thanks, Will


These trucks with the flex fuel systems will not get as good of milage on E85. They are designed this way. I haven't heard of any kind of spark plug that will help you in this. It is kind of a trade off, better milage but gas is more expensive, E85 is cheaper and more enviromently freindly but gas milage suffers. I also have a 2006 Chevy but did not get the flex fuel for this reason. On my car I use it and the milage suffers a little but with the trucks you will see even less milage due to the fact that trucks get worse milage than cars to begin with.

Spark plug wiring diagram


I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.
