Default Missfiring Possible

So, high idle kicks on by itself, no big d, i can deal with that, but the exhaust pulses while its on, like the sound comin from the tail pipe is just wierd and fairly loud, definitly not normal, friend said it sounded like it was misfiring or something, maybe an injector is clogged maybe, cause idling normal it doesnt do it, and bombing down the road its fine, , feels a little tired unprogrammed, just wondering if theres a cheap fix or have to order up some new 50 horse ddps, aint ordering up some stock ones from bosch, barrrrffff

does it sound like this? if so it's going into 3cyl high idle warmup..... what are the ambient temperatures there when it does it?


it'll sound like it's missfiring cause technically it is.... only running on 3 cyl's

my truck used to do itbafter my high idle kicks on and i narrowed it down to the preditor, once it kicks in it kinda sounds like my truck is cammed. alot of people on the diablosport forums complain about the surge too, if you download the newest update it should take care of it, it worked for mine.
