Need help ASAP
I need some help with my super duty asap, I am heading out on a 15hr trip this weekend and now my truck is acting up, its a 06 F-250 with a V10 and an auto tranny, Last night I stood on it to pass some one and when it hit 3500-4000 the engine started sputtering and not wanting to shift, if I drive normal it runs and shifts fine, Tranny fluid is clean and full, air filter is brand new K&N, I havent had any problems with this truck up till now.
I just put a 3inch flow master muffler and 4inch tail pipe on it 2 days ago and this was the first night I really got to drive it for about 3hrs, it ran great all night then on my way home blaa.
Could the exhaust be to free flowing for it?
Im going to try a fuel filter tonight but if that dosent fix it then Im lost, any help would be greatfully apprecated from me and my son- whom Im am doing this little road trip for to get him a new little quad. Thanks Craig
