I dont think its out of ballance. I think we are on to somthing with the fuel system. I havent had achance to work on it this week. hope to have some time this weekend to check out the fuel system. The shudder/miss/stumble only happens at 3800 to 4000 rpm. @ idle and off idle it is fine. It ony happens when im on it hard and shifting out of first. We will see what happens.
Thanks for all help.
