I've had this truck for 2 years and it would periodically have a miss but then be fine for days, I have maybe 5 tanks of fuel threw it and the miss came back today worse then ever. I did a balance rate check and my # 4 injector is running at +15 I shut it down. I bled the fuel system and it did have a bit of air in it, I started it again and it was +3 until I gave it a little throttle and the miss came back and back to 11+ I dont have any fuel leaks and I am not running a factory filter housing. It's driving me nuts, when it did this before if I went out on the road and really got on it the truck would " kick it out " and be fine for almost an entire pulling season. When my # 4 goes to 15+ my #6 goes to -7 when it's running with out the miss it is all within specs no more then 4 in either direction. I've even cracked the injector line on #4 to see if I had an air lock with no such luck. I know I might need injectors but these are less then 7000 miles . They are 80 over exergys. Any ideas would be great
