Just bought the car, the guy said he never did valve lash, timing belt, or water pump so no major maintence was done, He replaced the spark plugs and wires. The car does run and drive and it drives good but it definatley has a problem it sounds like its running not clean because you will hear it clear up. Is it possible this is a bad fuel filter or the cats are plugged up. it has 205,000 miles and the guy I bought it from said he bought it at 120,000
