No, the exhaust is not supposed to put-put like my 120 does.

It is probably running too rich, which is an indication of old vacuum lines that are starting to crack. Or chunks of carbon buildup on the piston heads which can be removed with Seafoam treatment.

You should check the ATF for color and smell, and if there are any maintenance records. The timing belt is replaced every 70K miles, the tensioner lasts for a very long time but not the tensioner rollers.
