Hi,

My dealer had it for two days, and as I expected, found nothing wrong -- injectors test solid, no codes left, and absent the load from towing heavy, on hills, while hot, no way to get their equipment to register my issue. They report all fuel lines solid, the fuel cooler clean, and no leaks anywhere.

These are two guys who know the truck since new, have serviced it thoroughly and regularly, and otherwise have my confidence. So for now I'm going to drive on and see what the future holds.

They did offer a thought that freeing up the exhaust might help keep overall temps down and thus keep the returned fuel cooler. Coming from a dealership, I found that interesting. Any thoughts on that from anyone?
