Engine/Transmission (1998.5 - 2002) Miss at idle when warm???

[strehl]

It only misses when in neutral or park after I'm driving for a while and park and wait for the egts to drop. If I put it back into drive or reverse theres no miss. The only thing I can think of is I have a leaking injector that can't build enough pressure to pop open with the little amount of fuel thats needed to idle. But wouldn't it leak all the time and make my mileage drop and the exhaust to haze? I'm still getting 18-20mpg and no haze except on cold startup ( which it always did ) help please??

Did you cycle the key to pull any codes? That would be the first step.

Does it have bigger injectors in it

?

Stock injectors and no codes. truck has 178K on it. The miss started a couple months after I put a new VP in.
