I replaced cam and both knock sensors but the codes came back.Took to auto zone to have codes cleared and they came back. Do I need a special tool to clear them?? Also car his a hesitation or slight misfire at times. Please if anyone has any suggestions I would greatly appreciate it!!! Thanks

Any Generic Scanner will erase your codes, auto zone might not of done it properly.. a scanner that could do it costs around a $100..well worth it
