Default Re: Rich spike at 4k rpms

well i had to bump this cause the prob is still there. I have been playing with the safc and had the truck running a little better( not going 10-1) but never better then 11-1. it still sputters or bucks. if i pull more fuel at 4k. it is really bad. i try to level out the safc adj and it sees 10 again.i am now looking at leaning it out before 3500 rpms to see if it smooths out. i may need to advance the cam gears again but in this rig that is big $. ideas anyone.
