That is probably not the problem, but it was not a good idea. You should have made them buy you a new oil ring if you paid them for the install. It sounds like 1 of 2 things. You could have a vaccuum leak or your TPS sensor could be mis-adjusted. How quick is the rev bounce? What is the RPM at the bottom and at the top of the bounce?
