The balancer will not cause a hesitation but your timing could be off after replacement. Check your timing and go from there.

Replace harmonic balancer. Somone else took it off my daughter's car. She ordered the part, I payed for it and picked it up. Any critical details on replacing it.

Line up the keyslot on the balancer with the key on the crankshaft. Usually just tightening the bolt that keeps it in place is sufficient to intsall it. I am not sure how much pressure you will need to get it back on the crankshaft but it's easier to put one on than to take one off! Be sure and check it after a day or so. Just to make sure you got it back on and it hasnt loosened. I think there is a torque setting but without exact info, firmly installed should do.
