if i rev my engine in it revs fine and sounds good, but as soon as a start to drive it and especially if i punch it and it hits 4 grand it sputters and pops and starts to misfire, any other rpm its fine. now my question is what could this be and is spark effected by the load im putting on the motor by driving or is it a fuel issue?

Ive had a few cases where I was going crazy trying to figure out that same type of situation. Ended up being an EGR valve. Try unplugging the vacuum line on your ECR valve and see if that does anything
