After we put gas in the truck started acting funny, hooked the code reader in and it said bad coil. We changed all 8 coils, put in 8 new spark plugs changed the crank shaft position censor and an injector and its still reading Coil F is the problem. We have cleared the code after changing all these plus un hooked the battery for 30+ minutes. We need this fixed by the end of the month to pass inspection and need more ideas on how to fix it. any one have any other ideas?

 

Drain out some of your gas into a clear container. Let it sit for 30 minutes. See how much water is in it.
