2006 megacab 2 wheel drive 5.7 144,??? miles. A Month ago check engine light and code P0306. The shop found #6 coil saturated in oil and both plugs electrodes are gone. So they replaced the valve cover gaskets and plug seals. Replaced all 16 plugs and the #6 coil. Now 2 weeks after that same code P0306. It would idle rough but run fine at highway speeds. I took to shop and they found that the electrodes on #6 were gone again. They Replaced them and I ran a bottle of Lucas high mileage injection cleaner. Thinking that #6 wasn't getting enough fuel. So now another 2 weeks I get P0302 they find coil bad and both the plugs had no gap, they were smashed. So they gapped them and replaced the coil. Now how the heck do the plugs electrodes get smashed like that.

 

Sounds like the shop is taking you and your money for a ride.

 

Go somewhere else. Stop their madness.

they only charged for the coil pack didn't charge for labor.
