97 Tracer with an older engine
 

Hi all,

New to this forum. I am looking at a 97 Tracer that the previous owner put an earlier 1.9L in. The car starts and runs but it runs rough. From what I can see, they replaced the TPS and the IAC as well but the car still runs rough. It's only $600 but, should I even get into this mess or leave it alone and look for another car. If it's an easy fix, I will buy it as I really love my 97 escort and can pretty much interchange parts if the need arises. Really would appreciate any help.
