Transferring Back to Previous College Where I Didnt Do As Well?

My question is that i would like to transfer back to the university i first went to right out of high school, i made some bad decisions and ended up on academic suspension. That was 4 years ago. Now i have the right state of mind but the school i'm at doesn't offer the ABET accredited degree i want so i want to transfer back to my previous school. My only issue is that im afraid my GPA and grades from being there right out of high school will be tacked on to my GPA now. Am i correct in that and if so is there anything i can do to ... in a way ... erase my bad semesters at my first school?
