Ok here goes, i have my truck (in the sig) that has a noticable miss when the air temperature is below 40 deg or so. The colder it gets, the worse it is. But it only happens when the engine is under a slight load, not at idle, not at wot. The higher the chip is turned up the more noticable it is also. When the outside temp get above 50 or so I can turn the chip up as far as I want and I'll never feel it.Now my dad's truck is an '02, 6 spd, has a 70 hp bully dog chip on it also does the same thing. Not as noticable but its definitely there when it gets cold or when you throw a trailer behind it. My dad's spent a lot of time at different shops trying to figure this out. My neighbor's '01, 6 spd, edge ez, same miss. No codes on any of them.After doing a lot of reading and research a lot of ppl suggested a high pressure leak inside the head whether due to bad o-rings, crushed injector tubes, or maybe even bad injectors. Today I put new rv275 injectors in my dads truck with new tubes and o-rings as well. Felt pretty good when i test drove it this afternoon even with the trailer behind it. But i was skeptical and sure enough another terst drive this evening with a slightly colder temp confirmed it was still there. So its back to the drawing board, I'd like to get this fixed or else there's no reason to sink any more money into my truck looking for performance if its gonna keep missing. Just read on another forum to test the alternator, it might be sending a voltage spike. Luckily I'm a diesel tech in training so I have a test bench to use but I'm open to any suggestions. I figured if our 3 trucks have the same problem somebody else out there has to as well and know how to fix it. Thanks in advance for any help
