My LLY will act kinda strange when making hot starts in warm weather. It could be a Predator glitch, so I'll return to stock and see if it continues, but do any of you guys have a slight "stumble" (for lack of a better word) when you start up a warm engine that has only been shut off for a few minutes?

When my engine is completely cold or has cooled for a few hours, it fires and runs normally.

It seems relatively normal to me based on my experience with other diesels, but I just wanted to see what you guys think.

I haven't noticed it on mine. What level on the predator are you running right now, and did you notice it on other levels? How long ago did you change a fuel filter? Maybe it is a slight air problem?

I'm running the Predator on kill right now, but it seems to do it regardless of the tune I'm running. I haven't checked it out with the stock file, so I'll do that.

It's been about 8,000 miles on my stock filter and 6,000 miles (I think) on my secondary, so I would think these would both be OK.
