just a usless update the dealer replaced a whole lots of parts still havnt fixed it. have to get the parts list the guy paid a couple g's fopr the parts so he bitched about it till they gave him back all his money cause one of the workers screwed up and said you did need that.
another story another friend custom ordered a 2500 crew cab with a dirtymax only to have simular problem again the dealer replaced all the parts they could still wouldnt fix it they had to buy back his truck and give him another

 

what about crank or cam sensors? if the timing was being thrown way off would it do this and not set any codes?

 

have to see if they replaced them. it would only do it maybe once a day and only happen when leaving from a stop like a stop light ot stop sign.

 

map sensor issue .. it sounds like ... i been reading more on these exact issues.. might be able to clean ir up and or have to reaplce it ..
can u scan for that ?
