I feel like my car has lost performance in the low range of the rpm band. I used to be able to spin my tires without a problem (i do not do this a lot) and when I started to notice the power loss I attempted to get the tires to spin and they didnt. I don't know whether its the spark plugs or the timing belt or the fuel injectors but it is very frustrating because I just had the transmission replaced because or bad slipping. Im not sure if the new transmission is the issue but it doesnt feel like it. Please help
